From: Andrey Grodzovsky <andrey.grodzovsky@xxxxxxx> Let's just ignore the I2C_M_STOP hint from upper layer for SMU I2C code as there is no clean mapping between single per I2C message STOP flag at the kernel I2C layer and the SMU, per each byte STOP flag. We will just by default set it at the end of the SMU I2C message.
