Subject: [PATCH] matroxfb: fix regression with uninitalized fb_info->mm_lock
mutex
Remove redundant call to the matroxfb_update_fix() before matrox
frambuffer is registered.
This fixes a problem with uninitialized the fb_info->mm_lock mutex
introduced by the commit 537a1bf059f " fbdev: add mutex for fb_mmap
locking"
