Subject: [PATCH] GPU: ARM: Midgard: Adapt to the new mmap call checks.
|
|
|
|
Now, I don't know if this driver is just one of these "buggy" drivers
|
|
Linus is talking about, or if this is just standard GPU procedure.
|
|
|
|
Anyway, this patch is due to this change by Linus Torvalds :

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=be83bbf806822b1b89e0a0f23cd87cddc409e429
|
|
|
|
And the fix is inspired by :
