[v4,0/8] iio: Set default trigger device parent

Message

Gwendal Grignou March 9, 2021, 7:36 p.m. UTC

Each drivers are setting trig->dev.parent to a common value - usually.
Move that in boiler plate code.

The first patch set the parent pointer, the next is an automatic change
with spatch.
The remaining ones are straightforward manual changes.

Few drivers remain:
drivers/iio/adc/at91-sama5d2_adc.c
drivers/iio/adc/mxs-lradc-adc.c
trigger parent set to iio device instead of its parent.

drivers/iio/adc/dln2-adc.c
trigger parent not set.

drivers/iio/gyro/mpu3050-core.c
trigger allocated for iio device but parent set to iio device parent.

drivers/iio/imu/bmi160/bmi160_core.c
drivers/iio/imu/inv_mpu6050/inv_mpu_trigger.c
trigger allocated for iio device but parent set to mapped register device holder. Looks like iio device parent.

drivers/iio/trigger/stm32-lptimer-trigger.c
drivers/iio/trigger/stm32-timer-trigger.c
trigger allocated for device, but parent set to device parent.


Changes in v4:
- Allow lines to be greater than 80 characters.
- Document patches that manually remove trigger parent assignments
  better.
