Subject: gpu: nova-core: replace ARef<Device> with &'bound Device in SysmemFlush
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=17b6544ec14198b53bcd546f891b3b22d0a015b2;p=thirdparty%2Fkernel%2Flinux.git

gpu: nova-core: replace ARef<Device> with &'bound Device in SysmemFlush

Now that SysmemFlush is lifetime-parameterized, the ARef<Device> is
unnecessary -- a plain &'bound Device reference suffices.
