i2c-designware: i2c_dw_read: Remove redundant target address checker
I2c_dw_xfer_msg() also has the same target address inconsistency check, and furthermore it checks across all i2c_msg messages, while i2c_dw_read() walks through i2c_msg messages only with_ I2C_M_RD flag. That is, target address check in i2c_dw_read() is redundant and useless. Signed-off-by: Shinya Kuribayashi <shinya.kuribayashi@necel.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
