[PATCH RFT 1/2] i2c: tegra-bpmp: don't modify input variable in xlate_flags

From: Wolfram Sang
Date: Wed Mar 31 2021 - 03:52:48 EST


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.
