5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Aleksandr Mishin <amishin@xxxxxxxxxx>

[ 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.
