From: Christophe Jaillet <christophe.jaillet@wanadoo.fr> stable inclusion from stable-v5.10.94 commit b9ac866c23bb898c4650c19afe82aa51d6ea794f bugzilla: https://gitee.com/openeuler/kernel/issues/I531X9 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit e96d52822f5ac0a25de78f95cd23421bcbc93584 ] Commit 79ca6f74dae0 ("tpm: fix Atmel TPM crash caused by too frequent queries") has moved some code around without updating the error handling path. This is now pointless to 'goto out_err' when neither 'clk_enable()' nor 'ioremap()' have been called yet. Make a direct return instead to avoid undoing things that have not been done.
