matroxfb: avoid -Warray-bounds warning
The open-coded list_for_each_entry() causes a harmless warning: drivers/video/fbdev/matrox/matroxfb_base.c: In function 'matroxfb_register_driver': include/linux/kernel.h:856:3: warning: array subscript -98 is outside array bounds of 'struct list_head[1]' [-Warray-bounds] Use the normal list_for_each_entry instead. Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20201026194010.3817166-1-arnd@kernel.org
