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'...
