WARNING: drivers/staging/built-in.o(.init.text+0xdc): Section mismatch in reference from the function fsl_mc_bus_driver_init() to the function .exit.text:dprc_driver_exit()
The function __init fsl_mc_bus_driver_init() references
a function __exit dprc_driver_exit().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __exit annotation of
dprc_driver_exit() so it may be used outside an exit section.

Static inline functions are preferred over macros. The function is
placed in obd_class.h instead lprocfs_status.h because obd_class.h
includes header obd.h which contains definition of struct obd_device

staging: comedi: fix extreme case of comedi_nsamples_left()

`comedi_nsamples_left(s, nsamples)` returns the number of samples
remaining to complete an asynchronous command or the passed in
`nsamples`, whichever is lower.  However, it goes wrong in the extreme
case of setting the `nsamples` parameter to `UINT_MAX` when the number
of conversions per "scan" (`s->async->cmd.scan_end_arg`) is 1.  It uses
`comedi_nscans_remaining(s, nscans)` to determine the number of scans
remaining, or the parameter `nscans`, whichever is lower.  To determine
the parameter `nscans`, it divides `nsamples` by the number of
conversions per scan and adds 1.  The addition of 1 is to avoid setting
the parameter `nscans` to 0, as `comedi_nscans_remaining(s, nscans)`
treats that value specially.  However in the extreme case where
`nsamples` is `UINT_MAX` and the number of samples per scan is 1, the
addition of 1 to `nscans` overflows, producing the unwanted 0.

Fix it by refactoring new a function `__comedi_nscans_remaining(s,
nscans)` out of `comedi_nscans_remaining(s, nscans)`.  The new function
does everything except the special handling when `nscans` is 0.  Change
`comedi_nsamples_remaining()` to call the new function without adding 1
to `nscans` to avoid the overflow.

This overflow bug doesn't affect any of the current COMEDI drivers.  I
stumbled across it while changing to one of the drivers.

staging: fbtft: fix voltage settings for C-Berry28

This patch fixes some internal voltage settings for the C-Berry28 display.
The original example source files for the C-Berry28 as provided by
its vendor admatec contained six issues where a command parameter's value
didn't match its corresponding comment.
I've informed admatec about these discrepancies on 2015-08-25. In the
meantime, I've assumed the comments to be more reliable than the code,
and thus have used these values to write the initial C-Berry28 driver.
After having received a reply from admatec on 2015-10-16 that the issues
have been fixed in their example code, it has turned out that for the
voltages VCOM and AVDD, the code was indeed correct, but the comments
were wrong. This patch is meant to fix these two pending mistakes.
