Subject: [PATCH] staging: rtlwifi: Remove unnecessary conditions
Date: Mon, 29 Oct 2018 23:36:38 -0700	[thread overview]
Message-ID: <20181030063636.GA5098@k-vBox> (raw)

Remove conditions with no effect at four different sections. Issues found
by Coccinelle's semantic patch results for cond_no_effect.cocci. Edit two
statements to keep expressions on one line--one from Julia's feedback.
Eliminate checkpatch result, a line should not end with a parenthesis.
