[PATCH v3] i2c: bpmp-tegra: Ignore unknown I2C_M flags

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In order to not to start returning errors when new I2C_M flags are
added, change behavior to just ignore all flags that we don't know
about. This includes the I2C_M_DMA_SAFE flag that already exists.
