Subject: [PATCH 14/14] staging: r8188eu: the bcnhead parameter is always 0
Date: Sat,  9 Jul 2022 19:10:00 +0200	[thread overview]
Message-ID: <20220709171000.180481-15-martin@kaiser.cx> (raw)
In-Reply-To: <20220709171000.180481-1-martin@kaiser.cx>

The only caller of efuse_read_phymap_from_txpktbuf sets bcnhead to 0.
Remove this function parameter and simplify the function body.
