Subject: media: mn88473: reset stream ID reg if no PLP given
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2fb0e047f98f4dc9320857e86076191188829bcd;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

media: mn88473: reset stream ID reg if no PLP given

If the PLP given is NO_STREAM_ID_FILTER (~0u) don't try to set that into the PLP register. Set PLP to 0 instead.
