i2c: iproc: generate stop event for slave writes
When slave status is I2C_SLAVE_RX_END, generate I2C_SLAVE_STOP event to i2c_client. Fixes: c245d94ed106 ("i2c: iproc: Add multi byte read-write support for slave mode") Signed-off-by: Rayagonda Kokatanur <rayagonda.kokatanur@broadcom.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
