Subject: [PATCH 1/1] [media] ite-cir: initialize use_demodulator before using it
Date: Sat, 10 Sep 2016 18:59:49 +0200	[thread overview]
Message-ID: <20160910165949.3507-1-nicolas.iooss_linux@m4x.org> (raw)

Function ite_set_carrier_params() uses variable use_demodulator after
having initialized it to false in some if branches, but this variable is
never set to true otherwise.

This bug has been found using clang -Wsometimes-uninitialized warning
flag.

Fixes: 620a32bba4a2 ("[media] rc: New rc-based ite-cir driver for
several ITE CIRs")
