Hi Lee,
This one doesn't actually build:
CC [M] drivers/iio/common/st_sensors/st_sensors_core.o
drivers/iio/common/st_sensors/st_sensors_core.c: In function 'st_sensors_set_drdy_int_pin':
drivers/iio/common/st_sensors/st_sensors_core.c:211:4: error: 'err' undeclared (first use in this function)
drivers/iio/common/st_sensors/st_sensors_core.c:211:4: note: each undeclared identifier is reported only once for each
function it appears in
drivers/iio/common/st_sensors/st_sensors_core.c:228:3: error: label 'init_error' used but not defined
make[4]: *** [drivers/iio/common/st_sensors/st_sensors_core.o] Error 1
The following patch gets rid of these lines so I'm guessing you reorganised your patch
series then didn't check buildling them in the new order.
Please fix this up before reposting the remainder of the series.
