Subject: [media] adv7604/adv7842: replace FMT_CHANGED by V4L2_DEVICE_NOTIFY_EVENT
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=48519838cc915d1af7083662471d2eb939a024c9;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[media] adv7604/adv7842: replace FMT_CHANGED by V4L2_DEVICE_NOTIFY_EVENT

This makes it easier for the bridge driver to just passthrough such
events to the corresponding device node.
