From: Christophe JAILLET <christophe.jaillet@wanadoo.fr> stable inclusion from stable-5.10.65 commit 4d2823abd1fe4e21653b3efafdbefa012d9d38d4 bugzilla: 182361 https://gitee.com/openeuler/kernel/issues/I4EH3U Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit d2f42e09393c774ab79088d8e3afcc62b3328fc9 ] If no suitable DMA configuration is available, a previous 'bdc_phy_init()' call must be undone by a corresponding 'bdc_phy_exit()' call. Branch to the existing error handling path instead of returning directly.
