SubjectRe: [PATCH v8 00/10] Qualcomm video decoder/encoder driver
From
Date
Hi Stanimir,

It looks good to me. I do think that patch 01/10 shouldn't go through
media. This might mean that we have to drop the COMPILE_TEST dependency
on the media driver until this firmware driver patch gets merged, which
is fine with me as long as this is clearly stated in the commit log for
the media Kconfig. Let me know what you want to do with this.

I also saw some comments for patch 05/10, but I'm not sure if that would
block merging this driver or can be fixed afterwards.

Regards,

Hans
