Subject: [PATCH 2/2] staging: r8188eu: remove unused da parameter
Date:   Fri,  2 Dec 2022 10:25:25 +0100
Message-Id: <20221202092525.403887-3-martin@kaiser.cx>
In-Reply-To: <20221202092525.403887-1-martin@kaiser.cx>
References: <20221202092525.403887-1-martin@kaiser.cx>

Content-Transfer-Encoding: 8bit
Precedence: bulk

All callers of issue_probereq_p2p set the da parameter to NULL. Remove
this parameters and the code that runs only for da != NULL.
