Subject: [PATCH 02/17] drm/msm: a6xx: Refactor a6xx_sptprac_enable()
Date: Sun, 20 Jul 2025 17:46:03 +0530	[thread overview]
Message-ID: <20250720-ifpc-support-v1-2-9347aa5bcbd6@oss.qualcomm.com> (raw)
In-Reply-To: <20250720-ifpc-support-v1-0-9347aa5bcbd6@oss.qualcomm.com>

A minor refactor to combine the subroutines for legacy a6xx GMUs under
a single check. This helps to avoid an unnecessary check and return
early from the subroutine for majority of a6xx gpus.
