[PATCH 2/2] drm: Rely on mode_config data for fb_helper initialization
Gabriel Krisman Bertazi
krisman at collabora.co.uk
Wed Feb 1 18:20:08 UTC 2017
Instead of receiving the num_crts as a parameter, we can read it
directly from the mode_config structure. I audited the drivers that
invoke this helper and I believe all of them (but one, see below)
initialize the mode_config struct accordingly, prior to calling the
fb_helper.
The auditing was done by visual inspection, and the only potential issue I
identified was in STI, which should be prevented by the first patch in
the series.
I used the following coccinelle hack to make this transformation, except
for the function headers and comment updates. The first and second
rules are split because I couldn't find a way to remove the unused
temporary variables at the same time I removed the parameter.
