Subject: [PATCH AUTOSEL 5.6 35/68] media: allegro: fix type of gop_length in channel_create message

From: Michael Tretter <m.tretter@...gutronix.de>

[ Upstream commit 8277815349327b8e65226eb58ddb680f90c2c0c0 ]

The gop_length field is actually only u16 and there are two more u8
fields in the message:

- the number of consecutive b-frames
- frequency of golden frames

Fix the message and thus fix the configuration of the GOP length.
