Subject: Re: [PATCH v2 10/19] media: camss: Enable building

Hi,

(for everyone's information:)

This error is caused by a missing patch [1] which is needed by this patchset.

The relevant patch has been reviewed and accepted but merging was delayed
until there is a driver actually using the formats which the patch adds.

I'll include the relevant patch in my next version of the patchset so we
will avoid this error next time.

[1] https://git.linuxtv.org/sailus/media_tree.git/commit/?h=packed12-postponed&id=549c02da6eed8dc4566632a9af9233bf99ba99d8

Best regards,
Todor
