staging: rtl8192u: r8192U_core: remove forward declarations in .c file
Checkpatch was giving a "externs should be avoided in .c files" because
of these forward declarations. As these were not useful in this case,
they have been removed.
Clean-up the file by using a cleaner spacing around symbols and
words. Mostly use the automatic checkpatch whitespacing fixes.
This takes care of the consistent spacing errors reported by
checkpatch.

staging: comedi: usbduxfast: document strange ai maxdata
The subdevice 'maxdata' is typically a mask of the valid bits that can
be returned by a subdevice, (1 << bits) - 1. The analog inputs of this
device have a resolution of 12-bits so the 'maxdata' should be 0x0fff.
But, this hardware can produce a value of 0x1000 indicating an overflow
from the ADC. The comedilib library's comedi_to_phys() function will
then return NAN when this value is read from the hardware.
Add a comment to clarify the strage 'maxdata' value.

This (*insn_config) does not follow the comedi core API. It also
would not work as expected.
It appears to be trying to configure the analog input subdevice so
that the (*insn_read) would read multiple channels (data[0]) and
optionally enable the 15us delay (data[1]) needed for the multiplexor
to change channels between samples.
Unfortunately, the comedi core expects (*insn_read) operations to
return 1 or more samples for a single channel, which is what the
(*insn_read) in this driver does.
The (*insn_config) is also enabling the analog input end-of-conversion
interrupt. This isn't needed, and might be a problem since the driver
does not currently request and interrupt. The enable bit does not
need to be set for the end-of-conversion to occur in the interrupt
status register.
Remove the (*insn_config) and modify the (*insn_read) to automatically
handle the 15us delay when needed.
