Hi all,

After merging the fbdev tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

Introduced by commit fb21c2f42879 ("fbdev: Add FOURCC-based format
configuration API").

The following patch should fix the issue. Florian, are you fine with it, or
would you rather modify the initializers to be name-based ?

Subject: [PATCH] fbdev: matroxfb: Fix compilation after fb_var_screeninfo change

Commit fb21c2f42879 ("fbdev: Add FOURCC-based format configuration API")
modified the layout of the fb_var_screeninfo structure. Update the
static initializers in the matroxfb driver accordingly.
