[PATCH 4.4 39/42] [media] ite-cir: initialize use_demodulator before using it

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nicolas Iooss <nicolas.iooss_li...@m4x.org>

commit 7ec03e60ef81c19b5d3a46dd070ee966774b860f upstream.

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")
