* fbdev: omapfb: off by one in omapfb_register_client()Dan Carpenter2018-07-241-1/+1
| | | | | | | | | | The omapfb_register_client[] array has OMAPFB_PLANE_NUM elements so the > should be >= or we are one element beyond the end of the array.

* video: omap: Improve a size determination in omapfb_do_probe()Markus Elfring2018-04-261-1/+1
| | | | | | | | | | | | Replace the specification of a data structure by a pointer dereference as the parameter for the operator "sizeof" to make the corresponding size determination a bit safer according to the Linux coding style convention. This issue was detected by using the Coccinelle software.

* fbdev: omapfb: delete check_required_callbacks()Aaro Koskinen2017-04-141-15/+0
| | | | | | | | | | | | | Commit 561eb9d09a93 ("fbdev: omap/lcd: Make callbacks optional") made panel callbacks optional but forgot to update check_required_callbacks(). As a result many (all?) OMAP systems using omapfb will crash at boot. Fix by deleting the whole function.

* fbdev: omap/lcd: Make callbacks optionalLars-Peter Clausen2017-01-301-11/+20
| | | | | | | | | | | Most OMAP FB LCD drivers don't have anything to do in their panel callbacks. This leads to a large set of empty boilerplate functions in the panel drivers. Make those callbacks optional by checking if they are set before calling them. This allows those boilerplate functions to be removed.

* fbdev: kill fb_rotateRasmus Villemoes2016-02-261-22/+0
| | | | | | | | | | | | The fb_rotate method in struct fb_ops is never actually invoked, and it's been that way in the entire history of git (in fact, the last occurrence of the string '->fb_rotate' vanished over 10 years ago, with b4d8aea6d6, and that merely tested whether the callback existed). So remove some dead code and make struct fb_obs a little smaller. Signed-off-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

* video/omap: fix modular buildArnd Bergmann2014-05-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | The framebuffer layer can be a loadable module, which forces omapfb to be a module as well. However, this breaks the lcd drivers, which are linked into the omapfb driver but each have their own module_init() function. To solve this, we split out the lcd drivers into separate modules and export omapfb_register_panel, which is the only interface required between the main omapfb driver and the lcd panel drivers. We also have to introduce a new Kconfig symbol for H3, since that lcd driver has a dependency on TPS65010, which we can express better in Kconfig than Makefile syntax.

* video: move fbdev to drivers/video/fbdevTomi Valkeinen2014-04-171-0/+1971
The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.
