Subject: [PATCH 2/9] media: vicodec: add field 'buf' to fwht_raw_frame
Date: Sat, 9 Feb 2019 05:54:20 -0800 [thread overview]
Message-ID: <20190209135427.20630-3-dafna3@gmail.com> (raw)
In-Reply-To: <20190209135427.20630-1-dafna3@gmail.com>
Add the field 'buf' to fwht_raw_frame to indicate
the start of the raw frame buffer.
This field will be used to copy the capture buffer
to the reference buffer in the next patch.
