Subject: [PATCH 0/3] media: allegro: fixes and improvements

Several fixes and improvements for the Allegro DVT video IP encoder.
These relate to race conditions that occur when multiple streams are used
simultaneously.
The problems could be reproduced on a ZCU-104 eval board with VCU firmware
version 2019.2 on various kernel versions (6.4, 6.12 and 6.16).
It is highly likely that these problems can also occur with other firmware
versions.
