Subject: i965/screen: Report the correct number of image planes
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9c52aef7d7858058712c0f5926e324af052690df;p=mesa.git

i965/screen: Report the correct number of image planes

For non-CCS images, we were reporting just one plane even though they
may have multiple in the case of YUV.
