Revert "fb: Initialize fb_info mutexes in framebuffer_alloc()"
This reverts commit 4148df9b0f38bdd362dd91d52076926c11cbe5a9. Let's hope that the mm_lock initialization is now correct with all drivers, following Krzysztof's patches. Requested-by: Krzysztof Helt <krzysztof.h1@poczta.fm> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
