[PATCH v2 0/7] Add helper method hid_sensor_adjust_channel_bit_mask()

[PATCH v2 0/7] Add helper method hid_sensor_adjust_channel_bit_mask()

[Natália Salvino André]

This patch series introduces a generic helper function to handle channel bit mask adjustments
for HID sensors. Currently, multiple drivers implement identical logic for this task

Natália Salvino André (7):
  iio: HID: Add helper method hid_sensor_adjust_channel_bit_mask()
  iio: accel: HID: Replace method accel_3d_adjust_channel_bit_mask()
  iio: gyro: HID: Replace method gyro_3d_adjust_channel_bit_mask()
  iio: light: HID: Replace method als_adjust_channel_bit_mask()
  iio: light: HID: Replace method prox_adjust_channel_bit_mask()
  iio: magnetometer: HID: Replace method
    magn_3d_adjust_channel_bit_mask()
  iio: pressure: HID: Replace method press_adjust_channel_bit_mask()

Indentation is broken. Taking into account that the last line is too long when
properly indented, perhaps

		hid_sensor_adjust_channel_bit_mask(channels,
				CHANNEL_SCAN_INDEX_X + i,
				st->accel[CHANNEL_SCAN_INDEX_X + i].size);

Which makes it most right and under 80 limit.

This message should be wrapped on ~72 characters. Some of the maintainers may
use cover letter as fake-merge commit message. And even if not, the standards
in the kernel for the cover letter and commit messages are the same in terms of
writing rules.

Basically this is the biggest issue in the whole series: missed proper
indentation / wrapping.

Code wise looks good, thanks for doing this!
