Subject: [PATCH v2 0/6] Add missing format_mod_supported functions

Hi all,

This patchset supersedes [1]. Now the title is a bit misleading, but
I left it this way to (hopefully) facilitate the maintainers' work.

A little context: Originally, I sent a patch adding modifiers to the
VKMS driver and Simon Ser kindly reviewed it and pointed out that
"format_mod_supported" was missing [2].
I asked if the docs were incorrect or if it was a bug in
"create_in_format_blob".

In the first version of this series, Simon Ser and Dmitry Baryshkov
agreed [1] that the code should behave as documented and
"create_in_format_blob" should be changed.

This second version implements the required changes and drops the
"format_mod_supported" in the drivers that can use the default
implementation.

Jose
