Subject: [media] cec: zero counters in cec_received_msg()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8991a63d1a8a01938932319c8b98f5a3420a0bb2;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[media] cec: zero counters in cec_received_msg()

Make sure the TX counters are zeroed in the cec_msg struct.
Non-zero TX counters make no sense when a message is received,
and applications should not see non-zero values here.
