Subject: Re: [PATCH 1/2] media: vimc: get pixformat info from v4l2_format_info
to avoid code repetition

Thanks for the patch, but the patch format is broken and I'm not able to
apply it :(
I recommend using git send-email or some email client that doesn't mess
up with the formatting.
Before re-sending the patch, please make sure you are able to send in the
correct format first to yourself, and that you are able to apply the email
from the mailing list on top or media/master.
Feel free to contact me directly if you want help with this.
Regards,
Helen
