From: Francisco Jerez Date: Fri, 18 Sep 2015 16:42:55 +0000 (+0200) Subject: clover: Move down canonicalization of memory object flags into validate_flags(). X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=92666b90c0db8bb51fd54bcf22db3d288a5556e7;p=mesa.git clover: Move down canonicalization of memory object flags into validate_flags(). This will be used to share the same logic between buffer and image creation. v2: Make memory flag set constants local to validate_flags.
