ACK/Cmnt: [PATCH 0/1][SRU][OEM-5.10/H] Fix typec output on AMD Cezanne GPU

[Tim Gardner]

Acked-by: Tim Gardner <tim.gardner at canonical.com>

As Juerg mentioned, some hints as to the changes required for the 
backport would be handy. In this case there are 2 files missing for 
oem-5.10, and an easily resolved context adjustment for Hirsute/5.11.
