Subject: [PATCH] Initialise the struct fb_info mutexes in clcdfb_register()

Commit 4148df9b0 moved the fb_info.lock and fb_info.mm_lock mutex
initialisation from register_framebuffer() to framebuffer_alloc().
However, the AMBA CLCD driver wraps the struct fb_info in the clcd_fb
structure, the latter being allocated with kzalloc.
