Subject: [PATCH] scsi: arcmsr: clean up clang warning on extraneous parentheses

From: Colin Ian King <colin.king@...onical.com>

There are extraneous parantheses that are causing clang to produce a
warning so remove these.

Clean up 3 clang warnings:
equality comparison with extraneous parentheses [-Wparentheses-equality]
