Simplifying the code a bit. Also drop the RCU read side lock since the object is locked anyway.
Untested since I can't get the driver to compile on !ARM.
Cross-compiler install is pretty easy and you should have that for pushing drm changes to drm-misc :-)
I do have cross compile setups for some architectures, but I seriously can't do that for every single driver.
With only a bit of work we allowed MSM to be compile tested on other architectures as well now. That even yielded a couple of missing includes and dependencies in MSM which just don't matter on ARM.
The only ones you need is arm32 and arm64. -Daniel

Assuming this compiles, it looks correct.
Yes it does.
