[PATCH AUTOSEL 5.4 10/19] drm/msm/adreno: a5xx_power: Don't apply A540 lm_setup to other GPUs

[Sasha Levin]

From: Konrad Dybcio <konrad.dybcio@somainline.org>

[ Upstream commit 4a9d36b0610aa7034340e976652e5b43320dd7c5 ]

While passing the A530-specific lm_setup func to A530 and A540
to !A530 was fine back when only these two were supported, it
certainly is not a good idea to send A540 specifics to smaller
GPUs like A508 and friends.

[PATCH AUTOSEL 5.4 11/19] drm/msm: Ratelimit invalid-fence message

[Sasha Levin]

From: Rob Clark <robdclark@chromium.org>

[ Upstream commit 7ad48d27a2846bfda29214fb454d001c3e02b9e7 ]

We have seen a couple cases where low memory situations cause something
bad to happen, followed by a flood of these messages obscuring the root
cause.  Lets ratelimit the dmesg spam so that next time it happens we
don't lose the kernel traces leading up to this.
