Subject: crypto: tegra - Don't touch bo refcount in host1x bo pin/unpin
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f8c9c57d750346abd213ffed2ae3cacb0268e9f1;p=thirdparty%2Fkernel%2Flinux.git

crypto: tegra - Don't touch bo refcount in host1x bo pin/unpin

Since commit "gpu: host1x: Allow entries in BO caches to be freed",
host1x_bo_pin() and host1x_bo_unpin() handle the bo's refcount
themselves. .pin/.unpin callbacks should not adjust it.
