[PATCH v2] drm/imagination: Explicitly set CACHED flag on META FW

[Alexandru Dadu]

From: Matt Coster <matt.coster@xxxxxxxxxx>

For completeness, OR in the CACHED flags when we're not ORing in the
UNCACHED counterparts. One of these is probably zero, but (a) it isn't
evident just by reading these lines, and (b) the compiler will make it
disappear in that case.
