Subject: [PATCH 10/20] staging: r8188eu: simplify rtw_make_wlanhdr's error handling
Date:   Fri, 30 Dec 2022 19:06:36 +0100
Message-Id: <20221230180646.91008-11-martin@kaiser.cx>
In-Reply-To: <20221230180646.91008-1-martin@kaiser.cx>

Precedence: bulk

Simplify the error handling in rtw_make_wlanhdr. Exit immediately instead
of jumping to the end of the function. We don't have to do any clean-up.
