[PATCH 0/1] dell-laptop: Only install the i8042 filter when rfkill is active

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Matthew,

https://bugzilla.redhat.com/show_bug.cgi?id=1045807 has made me take a closer
look at the dell-laptop.c code-paths on devices which are not on the rfkill
whitelist. Compared to 3.12 there is one change on these devices, the
i8042 filter gets installed independently of the whitelist, and if a
wireless keycode is detected by the filter a dell_send_request(buf, 17, 11)
will be done to query the rfkill settings.

Although unlikely to be the cause of rhbz#1045807, or to cause any problems
(the old rfkill code had the same issue on blacklisted devices), it seems
better to change the code so that there are no functional differences at all
on non white-listed models. This patch does this, can you send it to Linus
for the 3.13 ?

Thanks & Regards,

Hans
