2018-12-20fbdev: fsl-diu: remove redundant null check on cmapWen Yang
The null check on &info->cmap is redundant since cmap is a struct inside fb_info and can never be null, so the check is always true. We may remove it.

2018-09-28fbdev: fsl-diu: get cpu node with of_get_cpu_nodeRob Herring
"device_type" use is deprecated for FDT though it has continued to be used for nodes like cpu nodes. Use of_get_cpu_node() instead which works using node names by default. This will allow the eventually removal of cpu device_type properties.

2018-07-24video: fbdev: fsl-diu-fb: Remove VLA usageKees Cook
In the quest to remove all stack VLA usage from the kernel[1], this moves the buffer off the stack (since it could be as much as 1024 bytes), and uses a new area in the cursor data structure. Additionally adds missed documentation and removes redundant assignments.

2014-04-17video: move fbdev to drivers/video/fbdevTomi Valkeinen
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.
