I fixed this checkpatch warning for you:

WARNING: quoted string split across lines
#391: FILE: drivers/i2c/busses/i2c-designware-slave.c:281:
+		"%#x STAUTS SLAVE_ACTTVITY=%#x : RAW_INTR_STAT=%#x"
+		" : INTR_STAT=%#x\n",

Nice, you fooled two code checkers by having code in comments :) No
need to fix, of course:

    SMATCH
drivers/i2c/busses/i2c-designware-slave.c:318 i2c_dw_irq_handler_slave warn: unused return: stat = i2c_dw_read_clear_intrbits_slave()
drivers/i2c/busses/i2c-designware-slave.c:329 i2c_dw_irq_handler_slave warn: unused return: stat = i2c_dw_read_clear_intrbits_slave()
    CPPCHECK
drivers/i2c/busses/i2c-designware-slave.c:329: style: Variable 'stat' is assigned a value that is never used.

Build warning:

  CC      drivers/i2c/busses/i2c-designware-slave.o
drivers/i2c/busses/i2c-designware-slave.c:173:5: warning: no previous prototype for ‘i2c_dw_reg_slave’ [-Wmissing-prototypes]
 int i2c_dw_reg_slave(struct i2c_client *slave)

I declared the function static to fix it.

Applied to for-next, thanks!
