ACPI: PMIC: Remove unneeded check in tps68470_pmic_opregion_probe()
[ 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.
