2014-12-04video: udlfb: Deletion of unnecessary checks before the function call "vfree"Markus Elfring1-6/+3
The vfree() function performs also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

The uvesafb_free() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.

2014-11-14simplefb: Change simplefb_init from module_init to fs_initcallHans de Goede1-1/+1
One of the reasons for having the simplefb nodes in /chosen, and doing explicit enumeration of the nodes there, is too allow enumerating them sooner, so that we get a console earlier on. Doing this earlier then fs_initcall is not useful, since the fb only turns into a console when fbcon intializes, which is a fs_initcall too.

2014-11-14fbcon: Change fbcon_init from module_init to fs_initcallHans de Goede1-1/+1
Various fb drivers register themselves before module_init so as to have a console as early as possible, this is of little use if fbcon does not initialize early too. Fbcon cannot initialize earlier then fs_initcall, because then the creation of /sys/class/graphics/fbcon will fail.
