X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dc199241624a2fd85d9b0d8303babd60feadd0e6;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[media] videodev2: Add V4L2_BUF_FLAG_LAST

This v4l2_buffer flag can be used by drivers to mark a capture buffer
as the last generated buffer, for example after a V4L2_DEC_CMD_STOP
command was issued.
