From: Dinghao Liu Date: Mon, 4 Dec 2023 07:41:56 +0000 (+0800) Subject: ASoC: wm_adsp: fix memleak in wm_adsp_buffer_populate X-Git-Tag: v6.6.7~138 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b8668fe7a5e88e859f7506a1b5ed58e6ce474f9c;p=platform%2Fkernel%2Flinux-starfive.git ASoC: wm_adsp: fix memleak in wm_adsp_buffer_populate [ Upstream commit 29046a78a3c0a1f8fa0427f164caa222f003cf5b ] When wm_adsp_buffer_read() fails, we should free buf->regions. Otherwise, the callers of wm_adsp_buffer_populate() will directly free buf on failure, which makes buf->regions a leaked memory.
