Subject: media: dst_ca: remove CA_SET_DESCR boilerplate
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d8bc60a90d0090b7cae1bd6296230d82f6cac455;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

media: dst_ca: remove CA_SET_DESCR boilerplate

This ioctl is not implemented at dst_ca driver. There's just
a boilerplate code there. Remove it, as it is unlikely that
anyone would implement it those days.
