Subject: drm/i915/gvt/kvmgt: remove some dead code
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5bf63fb40eacb7ed1f1de70ae30a597313fa9960;p=openwrt%2Fstaging%2Fblogic.git

drm/i915/gvt/kvmgt: remove some dead code

"caps.buf" is always NULL here and "caps.size" is always zero.  The code
is a no-op and can be removed.
