From b8953fce22928fc508fab9d3818f88d10e050804 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Thu, 12 Oct 2023 04:29:08 +0300 Subject: [PATCH] drm/msm/dsi: use msm_gem_kernel_put to free TX buffer [ Upstream commit 69b321b2c3df4f7e51a9de587e41f324b0b717b0 ] Use exiting function to free the allocated GEM object instead of open-coding it. This has a bonus of internally calling msm_gem_put_vaddr() to compensate for msm_gem_get_vaddr() in msm_get_kernel_new().
