Subject: [PATCH 5.4 09/23] drm/msm/adreno: a5xx_power: Dont apply A540 lm_setup to other GPUs

From: Konrad Dybcio <konrad.dybcio@...ainline.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.
