drm/exynos: gsc: fix wrong bitwise operation for swap detection
The bits for rotation are not used as exclusively. So GSC_IN_ROT_270 can
not be used for swap detection. The definition of it is same with
GSC_IN_ROT_MASK. It is enough to check GSC_IN_ROT_90 bit is set or not to
check whether width / height size swapping is needed.

libnvdimm: fix namespace seed creation
A new BLK namespace "seed" device is created whenever the current seed
is successfully probed. However, if that namespace is assigned to a BTT
it may never directly experience a successful probe as it is a
subordinate device to a BTT configuration.
The effect of the current code is that no new namespaces can be
instantiated, after the seed namespace, to consume available BLK DPA
capacity. Fix this by treating a successful BTT probe event as a
successful probe event for the backing namespace.

Commit 4104d326b670 ("ftrace: Remove global function list and call function
directly") simplified the ftrace code by removing the global_ops list with a
new design. But this cleanup also broke the filtering of PIDs that are added
to the set_ftrace_pid file.
Add back the proper hooks to have pid filtering working once again.

Input: goodix - fix touch coordinates on WinBook TW100 and TW700
The touchscreen on the WinBook TW100 and TW700 don't match the default
display, with 0,0 touches being reported when touching at the bottom
right of the screen.
It's unfortunately impossible to detect this problem with data from the
DSDT, or other auxiliary metadata, so fallback to quirking this specific
model of tablet instead.
Devices may declare more LEDs than what is known to input-leds
(HID does this for some devices). Instead of showing ugly warnings
on connect and, even worse, oopsing on disconnect, let's simply
ignore LEDs that are not known to us.

DMA transfers must be greater than the watermark level size. spi_imx->rx_wml
and spi_imx->tx_wml contain the watermark level in 32bit words whereas struct
spi_transfer contains the transfer len in bytes. Fix the check if DMA is
possible for a transfer accordingly. This fixes transfers with sizes between
33 and 128 bytes for which previously was claimed that DMA is possible.

mmc: sdhci-pxav3: fix platform_data is not initialized
pdev->dev.platform_data is not initialized if match is true in function
sdhci_pxav3_probe. Just local variable pdata is assigned the return value
from function pxav3_get_mmc_pdata().
static int sdhci_pxav3_probe(struct platform_device *pdev) {
struct sdhci_pxa_platdata *pdata = pdev->dev.platform_data;
...
if (match) {
ret = mmc_of_parse(host->mmc);
if (ret)
goto err_of_parse;
sdhci_get_of_property(pdev);
pdata = pxav3_get_mmc_pdata(dev);
}
...
}
After commit 8d86e4fcccf6 ("mmc: sdhci-esdhc-imx: Call mmc_of_parse()"),
we do not need those duplicated parsing anymore.
Note: fsl,cd-controller is also deleted due to the driver does
not support controller card detection anymore after switch to runtime pm.
And there's no user of it right now in device tree.
wp-gpios is kept because we're still support fsl,wp-controller,
so we need a way to check if it's gpio wp or controller wp.
mmc: sdhci: make max-frequency property in device tree work
Device tree provides option to specify the max freqency with property
"max-frequency" in dts and common parse function mmc_of_parse() will
parse it and use this value to set host->f_max to tell the MMC core
the maxinum frequency the host works.
However, current sdhci driver will finally overwrite this value with
host->max_clk regardless of the max-frequency property.
This patch makes sure not overwrite the max-frequency set from device
tree and do basic sanity check.
mmc: sdhci-esdhc-imx: move all non dt probe code into one function
This is an incremental fix of commit e62bd351b("mmc: sdhci-esdhc-imx: Do not break platform data boards").
After commit 8d86e4fcccf6 ("mmc: sdhci-esdhc-imx: Call mmc_of_parse()"),
we do not need to run the check of boarddata->wp_type/cd_type/max_bus_width
again for dt platform since those are already handled by mmc_of_parse().
Current code only exclude the checking of wp_type for dt platform which
does not make sense.
This patch moves all non dt probe code into one function.
Besides, since we only support SD3.0/eMMC HS200 for dt platform, the
support_vsel checking and ultra high speed pinctrl state are also merged
into sdhci_esdhc_imx_probe_dt.
Then we have two separately probe function for dt and non dt type.
This can make the driver probe more clearly.
mmc: sdhci-esdhc-imx: fix cd regression for dt platform
Current card detect probe process is that when driver finds a valid
ESDHC_CD_GPIO, it will clear the quirk SDHCI_QUIRK_BROKEN_CARD_DETECTION
which is set by default for all esdhc/usdhc controllers.
Then host driver will know there's a valid card detect function.
Commit 8d86e4fcccf6 ("mmc: sdhci-esdhc-imx: Call mmc_of_parse()")
breaks GPIO CD function for dt platform that it will return directly
when find ESDHC_CD_GPIO for dt platform which result in the later wrongly
to keep SDHCI_QUIRK_BROKEN_CARD_DETECTION for all dt platforms.
Then MMC_CAP_NEEDS_POLL will be used instead even there's a valid
GPIO card detect.
This patch adds back this function and follows the original approach to
clear the quirk if find an valid CD GPIO for dt platforms.

mmc: omap_hsmmc: Handle BADA, DEB and CEB interrupts
Sometimes BADA, DEB or CEB error interrupts occur when sd card is
unplugged during data transfer. These interrupts are currently ignored
by the interrupt handler. But, this results in card not being
recognised on subsequent insertion. This is because mmcqd is waiting
forever for the data transfer(for which error occurred) to complete.
Fix this, by reporting BADA, DEB, CEB errors to mmc-core as -EILSEQ, so
that the core can do appropriate handling.

DTO/DCRC errors were not being informed to the mmc core since
commit ae4bf788ee9b ("mmc: omap_hsmmc: consolidate error report handling of
HSMMC IRQ"). This commit made sure 'end_trans' is never set on DTO/DCRC
errors. This is because after this commit 'host->data' is checked after
it has been cleared to NULL by omap_hsmmc_dma_cleanup().
Because 'end_trans' is never set, omap_hsmmc_xfer_done() is never invoked
making core layer not to be aware of DTO/DCRC errors. Because of this
any command invoked after DTO/DCRC error leads to a hang.
Fix this by checking for 'host->data' before it is actually cleared.

During a node failure, We need to suspend read balancing so that the
reads are directed to the first device and stale data is not read.
Suspending writes is not required because these would be recorded and
synced eventually.
A new flag MD_CLUSTER_SUSPEND_READ_BALANCING is set in recover_prep().
area_resyncing() will respond true for the entire devices if this
flag is set and the request type is READ. The flag is cleared
in recover_done().
md-cluster: fix bitmap sub-offset in bitmap_read_sb
bitmap_read_sb is modifying mddev->bitmap_info.offset. This works for
the first bitmap read. However, when multiple bitmaps need to be opened
by the same node, it ends up corrupting the offset. Fix it by using a
local variable.
Also, bitmap_read_sb is not required in bitmap_copy_from_slot since
it is called in bitmap_create. Remove bitmap_read_sb().
md: Return error if request_module fails and returns positive value
request_module() can return 256 (process exited) in some cases,
which is not as specified in the documentation before the
request_module() definition. Convert the error to -ENOENT.
The positive error number results in bitmap_create() returning
a value that is meant to be an error but doesn't look like one,
so it is dereferenced as a point and causes a crash.
