Subject: Re: [PATCH v3 0/9] Qualcomm video decoder/encoder driver
Hi Stanimir,
Overall it looks good. As you saw, I do have some comments but nothing major.
One question: you use qcom as the directory name. How about using qualcomm?
It's really not that much longer and a bit more obvious.
Up to you, though.
Regards,
Hans
