Clip memory range to screen-buffer size to avoid out-of-bounds access in fbdev deferred I/O's damage handling. Fbdev's deferred I/O can only track pages. From the range of pages, the damage handler computes the clipping rectangle for the display update. If the fbdev screen buffer ends near the beginning of a page, that page could contain more scanlines. The damage handler would then track these non-existing scanlines as dirty and provoke an out-of-bounds access during the screen update. Hence, clip the maximum memory range to the size of the screen buffer. While at it, rename the variables min/max to min_off/max_off in drm_fb_helper_deferred_io(). This avoids confusion with the macros of the same name. Reported-by:

Implement DRM's aperture helpers under video/ for sharing with other sub-systems. Remove DRM-isms from the interface. The helpers track the ownership of framebuffer apertures and provide hand-over from firmware, such as EFI and VESA, to native graphics drivers. Other subsystems, such as fbdev and vfio, also have to maintain ownership of framebuffer apertures. Moving DRM's aperture helpers to a more public location allows all subsystems to interact with each other and share a common implementation. The aperture helpers are selected by the various firmware drivers within DRM and fbdev, and the VGA text-console driver. The original DRM interface is kept in place for use by DRM drivers. v3: * prefix all interfaces with aperture_ (Javier) * rework and simplify documentation (Javier) * rename struct dev_aperture to struct aperture_range * rebase onto latest DRM * update MAINTAINERS entry Signed-off-by:

backlight_properties.fb_blank is deprecated. The states it represents are handled by other properties; but instead of accessing those properties directly, drivers should use the helpers provided by backlight.h. Instead of retrieving the backlight brightness in struct backlight_properties manually, and then checking whether the backlight should be on at all, use backlight_get_brightness() which does all this and insulates this from future changes.

This started with work on the removal of backlight_properties' deprecated fb_blank field, much of which can be taken care of by using helper functions provided by backlight.h instead of directly accessing fields in backlight_properties. This patch series doesn't involve fb_blank, but it still seems useful to use helper functions where appropriate. Instead of retrieving the backlight brightness in struct backlight_properties manually, and then checking whether the backlight should be on at all, use backlight_get_brightness() which does all this and insulates this from future changes.

Instead of setting the power state by manually updating fields in struct backlight_properties, use backlight_enable() and backlight_disable().

Instead of retrieving the backlight brightness in struct backlight_properties manually, and then checking whether the backlight should be on at all, use backlight_get_brightness() which does all this and insulates this from future changes. Instead of manually checking the power state in struct backlight_properties, use backlight_is_blank(). While we're at it, drop .fb_blank from the initialisation function; it is deprecated, and this helps make progress towards enabling its removal. This change makes no functional difference since FB_BLANK_UNBLANK is the default value. Signed-off-by:
