staging: rtl8192ee: Correct bitmask in comparsion

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

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.

staging: comedi: addi_apci_1564: clean up apci1564_interrupt()

Remove the checks for interrupts from unknown sources.  This situation
should never occur and the checks were doing nothing to help the
situation.

Also, the portion of the function for handling counter interrupts is
reapeated four times (once for each counter), but is completely identical
save for the register is is accessing, so we can handle all four counters
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.

digital input interrupts when the configuration operation is
COMEDI_DIGITAL_TRIG_DISABLE.  However, this is incorrect as the device reset
