* | lcd: fix oops if driver only interested in .set_powerBen Dooks2008-11-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The LCD driver core calls LCD drivers when either the blanking state or the display mode has changed, but does not make any check to see if the called driver has a .set_mode method. This means if a driver only has a .set_power method then the system will OOPS on changing mode (and with the console semaphore held so you cannot easily see the problem). Fix the problem by ensuring that either callback is valid before use.

* fbdev: fix fb_compat_ioctl() deadlocksGeert Uytterhoeven2008-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | commit 3e680aae4e53ab54cdbb0c29257dae0cbb158e1c ("fb: convert lock/unlock_kernel() into local fb mutex") introduced several deadlocks in the fb_compat_ioctl() path, as mutex_lock() doesn't allow recursion, unlike lock_kernel(). This broke frame buffer applications on 64-bit systems with a 32-bit userland. commit 120a37470c2831fea49fdebaceb5a7039f700ce6 ("framebuffer compat_ioctl deadlock") fixed one of the deadlocks. This patch fixes the remaining deadlocks: - Revert commit 120a37470c2831fea49fdebaceb5a7039f700ce6, - Extract the core logic of fb_ioctl() into a new function do_fb_ioctl(), - Change all callsites of fb_ioctl() where info->lock is already held to call do_fb_ioctl() instead, - Add sparse annotations to all routines that take info->lock.

Therefore, these macros should return (void __iomem *) cookies, not integer values. Doing this improves typechecking, and means we can find those places where, eg, DMA controllers are incorrectly given virtual addresses to DMA to, or physical addresses are thrown through a virtual to physical address translation.
