staging: rtl8188eu: Remove struct evt_priv and its uses
c2h_wk (work_struct) is naver scheduled to handle events,
so no use of keeping event data.
And also function rtw_hal_c2h_handler() responsible for handling c2h events,
is a dummy function.

driver now validates input as well.
staging: rtl8712: remove wrapper function _init_workitem()
The inline function _init_workitem() is just a wrapper around INIT_WORK().
Oddly, this wrapper accepts 3 parameters while INIT_WORK() only accepts 2.
The third parameter is unused.

In iowrite32() calls, the address of registers was expressed as e.g.
&ep->registers[fpga_msg_ctrl_reg]. This changes to the more common format
e.g. ep->registers + fpga_msg_ctrl_reg.
There is no functional change.

staging: rtl8188eu: use GFP_ATOMIC under spinlock
We're holding a spinlock here so we can't do sleeping allocations.
The call tree is:
rtw_sta_flush() <-- takes spin_lock_bh(&pstapriv->asoc_list_lock);

Originally these calls were rtw_zmalloc() and then we switched them to
kzalloc() in fadbe0cd5292 ('staging: rtl8188eu:Remove rtw_zmalloc(),

checker. The original code was buggy as well but my static checker

staging: goldfish: Introduce the use of managed interfaces
This patch introduces the use of managed interfaces like devm_kzalloc,
devm_ioremap, dmam_alloc_coherent, devm_request_irq and does away with
the calls to functions to free the allocated memory in the probe and
remove functions. Also, the labels are removed in the probe function.

Instead of using an own copy of struct net_device_stats in struct

netdev->stats, which is the default in dev_get_stats().
Furthermore, convert prefix increment of stats counters to the more
common postfix increment idiom.

- Add endianness annotations.

staging: emxx_udc: Fix build error
‘strict_strtol’ is deprecated. Use kstrtol instead. Fixes the following
build error:
drivers/staging/emxx_udc/emxx_udc.c:3288:3: error: implicit declaration of function ‘strict_strtol’
The issue is discovered by static checker. The proposed change (0x000c0
-> 0x000c) is likely correct because:
1. 16-bit `map` holds value coming from struct
ieee80211_vht_mcs_info.tx_mcs_map, which is described so: "TX MCS map 2
bits for each stream, total 8 streams". The changed code refers to case
of 2 TX streams, and 0x000c mask filters two bits related to the second
stream. Some codelines below 0x0003 mask is used to test first stream.
2. Mask 0x000c is used 3 more times in that place.
3. Specifying 5 digits of hex value is uncommon, especially while working
with `u16` variable. So likely the trailing zero is a typo.

staging: comedi: usbduxsigma: fixing rounding error in the range struct
The AD converter on the usbsigma turns vref (2.5V/2) into the
binary value 0x780000. However the full scale range goes up to
0x800000 so that vref/2 needs to be upscaled by 0x800000/0x780000
which is 1.06bar. In the driver it's been 1.06 without the infinite
6666. I've put the fraction in the code so that the compiler can
calculate the most precise scaling value by itself.

staging: comedi: allow COMEDI_BUFINFO, COMEDI_CANCEL and COMEDI_POLL on locked subdevice
Comedi subdevices can be locked for mostly exclusive access by a
particular file object by means of the COMEDI_LOCK ioctl. Some
operations disregard the lock. For example, the read() and write() file
operations are allowed for the file object that set up an asynchronous
command on the subdevice (making it "busy") regardless of whether it is
locked.
The COMEDI_BUFINFO, COMEDI_CANCEL and COMEDI_POLL ioctls are also
associated with the file object that made the subdevice "busy" with a
command. They currently obey the exclusive access lock on the subdevice
as well, but it makes more sense for them to ignore it like the read()
and write() file operations. Remove the exclusive subdevice access
checks for these ioctls.

Also, the portion of the function for handling counter interrupts is

with a for loop.
Finally, the interrupt handler is incorrectly setting and then checking
devpriv->timer_select_mode before processing some of the triggered
interrupts, so just remove all occurrences of this.
