Subject: [media] ite-cir: initialize use_demodulator before using it
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7ec03e60ef81c19b5d3a46dd070ee966774b860f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[media] ite-cir: initialize use_demodulator before using it

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")
