Subject: [PATCH v1 12/18] media: uapi: Add a control for HANTRO driver
Date:   Wed, 17 Feb 2021 09:03:00 +0100

The HEVC HANTRO driver needs to know the number of bits to skip at
the beginning of the slice header.
That is a hardware specific requirement so create a dedicated control
that this purpose.
