X-Git-Tag: Ubuntu-5.10.0-12.13~20052^2~13^2~5
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=dc625537f7d4301a7e3f6a8476bd624b09508488;p=mirror_ubuntu-hirsute-kernel.git

drm/exynos: Use devm_clk_get in exynos_drm_g2d.c

devm_clk_get is device managed and makes error handling and exit code
simpler.
