From: Aleksandr Mishin <amishin@t-argos.ru> stable inclusion from stable-v4.19.323 commit 90d62b53d8281851d8cff06f3a663dd169c5536a category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBBN6V Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 07442c46abad1d50ac82af5e0f9c5de2732c4592 ] In tps68470_pmic_opregion_probe() pointer 'dev' is compared to NULL which is useless. Fix this issue by removing unneeded check. Found by Linux Verification Center (linuxtesting.org) with SVACE.
