#1448442 — [PATCH 1/1] drm/sti: use new Reset API

Since 0b52297f228 ("reset: Add support for shared reset controls") the
new Reset API now demands consumers choose either an *_exclusive or
a *_shared line when requesting reset lines.

Seems like this patch also changes the behavior from being exclusively
managed to shared. Is this intentional? If so, it's probably worth
changing you commit message to be a little less innocuous.

Interesting turn of phrase.  You would like the commit message to be
more "harmful or offensive".  I'm sure I can rustle something up to
suit!

... or I could just mention why I'm changing the behaviour? ;)

v2 to follow.
