Subject: [PATCH RFT 1/2] i2c: tegra-bpmp: don't modify input variable in xlate_flags
Date: Wed, 31 Mar 2021 09:51:40 +0200	[thread overview]
Message-ID: <20210331075141.22227-2-wsa@kernel.org> (raw)
In-Reply-To: <20210331075141.22227-1-wsa@kernel.org>

Since commit bc1c2048abbe ("i2c: bpmp-tegra: Ignore unknown I2C_M
flags") we don't need to mask out flags and can keep the input variable
as is to save quite some lines.
