Subject: [PATCH] platform/x86: dell_rbu: fix assignment in if condition

From: Darshan Rathod <darshanrathod475@...il.com>

Refactor to remove assignments from inside if conditions, as required
by kernel coding style. This improves code readability and resolves
checkpatch.pl warnings:

    ERROR: do not use assignment in if condition
