[PATCH 0/5] drm/ssd130x: A few enhancements and cleanups

[Thomas Zimmermann]

Hi Javierm,

I've read through the patches and they look correct to me.

Reviewed-by: Thomas Zimmermann <tzimmermann at suse.de>

But I had one question about the page size. You round up to multiples of 
page_size in several places. That could lead to an out-of-bounds access. 
Do you need to allocate GEM buffers to be multiples of page_size as well?

Best regards
Thomas
