Subject[PATCH] framebuffer drivers: static zero initializers removal
Hi all,

IMHO subject is selfexplaining. Affected files: amifb.c, atafb.c, clgenfb.c,
cyberfb.c, tdfxfb.c, tgafb.c, vesafb.c, vfb.c, vga16fb.c, vgacon.c, virgefb.c
and most importantly skeletonfb.c :)

All patches are extremely simple, except patch for TGA framebuffer which
adds missing pci_enable_device() call.

Best regards.
