[PATCH 5.5 051/257] media: allegro: fix type of gop_length in channel_create message

From: Greg Kroah-Hartman
Date: Thu Apr 16 2020 - 11:47:40 EST


From: Michael Tretter <m.tretter@xxxxxxxxxxxxxx>

[ 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.
