The base917c_format isn't exported, so make it static to avoid the following warning: drivers/gpu/drm/nouveau/dispnv50/base917c.c:26:1: warning: symbol 'base917c_format' was not declared. Should it be static? Signed-off-by: Ben Dooks <ben.dooks at codethink.co.uk> --- drivers/gpu/drm/nouveau/dispnv50/base917c.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git

Hi! While trying to get CLUT support for the atmel_hlcdc driver, and specifically for the emulated fbdev interface, I received some push-back that my feeble in-driver attempts should be solved by the core. This is my attempt to do it right. I have obviously not tested all of this with more than a compile, but patches 1 through 5 are enough to make the atmel-hlcdc driver do what I need. The rest
