The struct avs_modcfg_ext structure has a flexible array member for the pin_fmts array, and the size should be calculated using struct_size to prevent the potential for overflow with the allocation.

I've explicitly asked for the Signed-off-by to be the last line in the tag area. Also, while I'm the author of the driver, nothing is being merged by me - Mark is the maintainer for the ASoC subsystem, so you should send messages to him and keep appropriate people/list in Cc (email's Cc list, no need for every entry to be represented by an equivalent 'Cc:' tag within a commit message simultaneously).

Will fix in v2. Sorry about this, I wasn't aware what the convention was. I am used to thinking about the tags in order of when the event occurred, "I signed off that this is my work and can submit it first, then it was reviewed". The Cc tags were there because it helps me keep track of who to send the patch to but I can do that separately and drop them from the commit message.

Thanks, Jake

TLDR:

Drop both CC tags, not needed. Have both Reviewed-by _before_ Signed-off-by. Then update the email's --cc/--to so that it reflects the actual structure of the subsystem.
