Re: [PATCH 01/12] drm/i915/guc: Sanitize GuC client initialization

It's a good practice to use "git am" to apply the original patch and
then "git commit --amend" to it, so that the "From: " field stays
intact. Or use git commit --amend --author="John Doe <foo@xxxxxxx>" but
that is more prone to typos.

The R-b should probably be after S-o-b if it was to last version.
