hmm the whole block reads:

        case REG_STATE_STATE_DATA:
                if (cur_msg->flags & I2C_M_RD) {
                        efm32_i2c_recv_next_byte(ddata);
                } else {
                        /* wait for Ack or Nack of slave */
                }
                break;

so just removing the braces does the wrong thing. Is this a false
positive checkpatch warning? Andy? Joe?

I can make it:

		if (cur_msg->flags & I2C_M_RD)
			efm32_i2c_recv_next_byte(ddata);
		/* in the write case wait for Ack or Nack of slave */

but I consider the version above more readable.

Best regards
Uwe
