[PATCH 0/7] Adis IRQ fixes and minor improvements

The primary goal of this series was to fix the return value on some
trigger handlers as spotted in [1]. While doing it, I found some minor
improvements that I think are simple enough to include in this series.

As for the first 2 patches, I opted to not do any functional change so
I'm keeping the 'if (!adis->buffer)' check. However, 'adis-buffer' is
allocated in 'update_scan_mode' hook which means we should be sure that
the buffer is allocated and the check is really not needed. I did not
went into the details but is there any way for the trigger handler to be
called before the 'update_scan_mode' hook? If not, I'm happy in sending
a v2 where we just remove the 'if'...
