Subject: [PATCH 3/4] staging: r8188eu: Remove self assignment in get_rx_power_val_by_reg()
Date: Tue,  3 Aug 2021 15:36:08 -0700	[thread overview]
Message-ID: <20210803223609.1627280-4-nathan@kernel.org> (raw)
In-Reply-To: <20210803223609.1627280-1-nathan@kernel.org>

Clang warns:

drivers/staging/r8188eu/hal/rtl8188e_rf6052.c:344:13: warning:
explicitly assigning value of variable of type 'u32' (aka 'unsigned
int') to itself [-Wself-assign]
                        writeVal = writeVal;
                        ~~~~~~~~ ^ ~~~~~~~~
1 warning generated.

Remove this branch as it is useless.
