[PATCH] [RESEND] drm/gma500: initialize gma_clock_t structures

[PATCH] [RESEND] drm/gma500: initialize gma_clock_t structures

[Arnd Bergmann]

The two functions pass a partially initialized structure back to the
caller after a memset() on the destination.

This is not entirely well-defined, most compilers are sensible enough
to either keep the zero-initialization for the uninitialized members,
but gcc-4.4 does not, and it warns about this:

drivers/gpu/drm/gma500/oaktrail_crtc.c: In function 'mrst_sdvo_find_best_pll':
drivers/gpu/drm/gma500/oaktrail_crtc.c:175: warning: 'clock.vco' may be used uninitialized in this function
drivers/gpu/drm/gma500/oaktrail_crtc.c:175: warning: 'clock.dot' may be used uninitialized in this function

drivers/gpu/drm/gma500/oaktrail_crtc.c:208: warning: 'clock.n' may be used uninitialized in this function

This adds an initialization at declaration time to avoid the warning
and make it well-defined on all compiler versions.

Dave or Daniel, I'm on sick leave and will be for some time to come.
Can one of you pick up this patch? Thanks.

Applied to drm-misc-next-fixes for 4.16, thx for your patch. Aside: Still
don't want commit rights? :-)

Thanks!

> Aside: Still don't want commit rights? :-)

I think I'm fine without. While I do tend to have a backlog on DRM
patches that I'd
like to get merged, they are generally of the kind that I should not
apply myself
without the maintainer being involved in some form, and then they can commit
it themselves.

Commit rights isn't for pushing unreviewed stuff (our scripts will
remind you of that if you try). But you could just volunteer someone
to review the entire pile and then push it, instead of nagging every
single slacking maintainer individually.

I understand, but I could also just nag someone to review and apply
the patches, right? Or do the committer and reviewer also need to
be separate people?
