Subject: [PATCH] staging: r8188eu: remove else after return and break statements
Date:   Wed, 13 Apr 2022 10:57:58 +0530
Message-Id: <20220413052759.4859-1-mahak_g@cs.iitr.ac.in>
Precedence: bulk

Else is not necessary after return and break statements, hence remove
it.

Reported by checkpatch:

WARNING: else is not generally useful after a break or return
