From: Tang Bin <tangbin@cmss.chinamobile.com> stable inclusion from stable-5.10.80 commit 949c5b6daa75aff41ff8861381be67337e133f5f bugzilla: 185821 https://gitee.com/openeuler/kernel/issues/I4L7CG Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit a472cc0dde3eb057db71c80f102556eeced03805 upstream. The function s5p_aes_probe() does not perform sufficient error checking after executing platform_get_resource(), thus fix it.
