Subject: [PATCH 12/14] staging: r8188eu: _offset is always 0 in efuse_phymap_to_logical
Date:   Sat,  9 Jul 2022 19:09:58 +0200
Message-Id: <20220709171000.180481-13-martin@kaiser.cx>
In-Reply-To: <20220709171000.180481-1-martin@kaiser.cx>
References: <20220709171000.180481-1-martin@kaiser.cx>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

The _offset parameter of iol_read_efuse is always 0. Remove the
parameter and use 0 in the function body.

We can now replace the bytewise copy from efuseTbl to pbuf with memcpy.
