Subject: gpu: host1x: Initialize firewall class to the job's one
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3833d16f1677e19098eb8cc0f0a54f6e209406f4;p=linux.git

gpu: host1x: Initialize firewall class to the job's one

The commands stream is prepended by the jobs class on the CDMA
submission, so that explicitly setting a module class in the commands
stream isn't necessary. The firewall initializes its class to 0 and the
command stream that doesn't explicitly specify the class effectively
bypasses the firewall.
