staging: iio: adc: Replace of_iomap() with devm_ioremap_resource()
The adc driver uses of_iomap() which doesn't request the resource and
isn't device managed so error handling is needed. of_iomap() is mainly
used in cases where there is no driver or struct device so a switch to
devm_ functions is required.
This patch switches to use devm_ioremap_resource() instead which
automatically requests the resource and is freed when the driver
detaches.
Removed the error handling to unmap I/O registers i.e.
iounmap() in probe and remove functions of this driver and
consequently removed an unnecessary label.

distinguished using bus-specific token).

device node from which the property value is to be read. It doesn't

staging/android/ion : fix a race condition in the ion driver
There is a use-after-free problem in the ion driver.
This is caused by a race condition in the ion_ioctl()
function.
A handle has ref count of 1 and two tasks on different
cpus calls ION_IOC_FREE simultaneously.
cpu 0 cpu 1
-------------------------------------------------------
ion_handle_get_by_id()
(ref == 2)
ion_handle_get_by_id()
(ref == 3)
ion_free()
(ref == 2)
ion_handle_put()
(ref == 1)
ion_free()
(ref == 0 so ion_handle_destroy() is
called
and the handle is freed.)
ion_handle_put() is called and it
decreases the slub's next free pointer
The problem is detected as an unaligned access in the
spin lock functions since it uses load exclusive
instruction. In some cases it corrupts the slub's
free pointer which causes a mis-aligned access to the
next free pointer.(kmalloc returns a pointer like ffffc0745b4580aa). And it causes lots of other
hard-to-debug problems.
This symptom is caused since the first member in the
ion_handle structure is the reference count and the
ion driver decrements the reference after it has been
freed.
To fix this problem client->lock mutex is extended
to protect all the codes that uses the handle.

probe. And moreover if the pci driver has failed to register then we
never need to unregister it. Lets just print the warning, perform the
cleanup and exit with the error code.

staging: dgnc: Break line after boolean operator
The preferred way to break up long math lines is to break after an arthimetic
or boolean operator. This patch fixes the checkpatch.pl warning:
Logical continuations should be on the previous line.

staging: dgnc: Fix block comment style
This patch fixes the block comment style.
1. The checkpatch.pl warning:
Block comments use a trailing */ on a separate line.
2. '====' separator is unnecessary and should not be used.
staging: vme: devices: Replace kzalloc with devm_kzalloc
Devm_ functions allocate memory that is released when a driver
detaches. Replace kzalloc with devm_kzalloc and remove corresponding
kfrees from probe and remove functions of a platform
device.
Unnecessary spi_set_drvdata() has been removed since the driver
core clears the driver data to NULL after device release or on
probe failure. There is no need to manually clear the device
driver data to NULL.
The Coccinelle semantic patch used to make this change is as follows:
@@
struct spi_device *spi;
@@
- spi_set_drvdata(spi, NULL);
// </smpl>
Due to this removal, variable `spi` was unused so dropped `spi`
