Currently, the driver updates the FIFO watermark inside both
update_scan_mode() and hwfifo_set_watermark(). Inside the IIO core,
hwfifo_set_watermark() is called immediately after update_scan_mode(),
making the first call to set_fifo_samples() redundant.
Remove the first call to set_fifo_samples(), and merge the
set_fifo_samples() function into the set_fifo_watermark()
function. Also, since fifo_set_size is always set inside of
update_scan_mode(), and it cannot be set to 0, remove the
zero check from set_fifo_samples().

bmc150_magn_remove() always returns zero. Make it return no value which
makes it easier to see in the callers that there is no error to handle.
Also the return value of i2c driver remove callbacks is ignored anyway.
This prepares making i2c remove callbacks return void, too.

Returning an error value in an i2c remove callback results in a generic
error message being emitted by the i2c core, but otherwise it doesn't
make a difference. The device goes away anyhow and the devm cleanups are

So instead of triggering the generic i2c error message, emit a more
helpful message if a problem occurs and return 0 to suppress the generic

The bluetooth code uses our bitmap infrastructure for the two bits (!)
of connection setup flags, and in the process causes odd problems when
it converts between a bitmap and just the regular values of said bits.
It's completely pointless to do things like bitmap_to_arr32() to convert
a bitmap into a u32. It shoudln't have been a bitmap in the first
place. The reason to use bitmaps is if you have arbitrary number of
bits you want to manage (not two!), or if you rely on the atomicity
guarantees of the bitmap setting and clearing.
The code could use an "atomic_t" and use "atomic_or/andnot()" to set and
clear the bit values, but considering that it then copies the bitmaps
around with "bitmap_to_arr32()" and friends, there clearly cannot be a
lot of atomicity requirements.
So just use a regular integer.
In the process, this avoids the warnings about erroneous use of
bitmap_from_u64() which were triggered on 32-bit architectures when
conversion from a u64 would access two words (and, surprise, surprise,
only one word is needed - and indeed overkill - for a 2-bit bitmap).
That was always problematic, but the compiler seems to notice it and
warn about the invalid pattern only after commit 0a97953fd2 ("lib: add
bitmap_{from,to}_arr64") changed the exact implementation details of
'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

It used to grab an extra reference to struct file rather than
just transferring to caller the one it had removed from descriptor
table. New variant doesn't, and callers need to be adjusted.
