Message-ID<sZaff-1qE-3@gated-at.bofh.it>
Hello Lee,

This series contains cleanups for the max77686 PMIC MFD driver.
The driver is only used in DT platforms and so all the code
related with the i2c_device_id table can be removed.

Best regards,
Javier

Changes in v2:
- Add Laxman's Acked-by tag to patch 1/4.
- Add Krzysztof's Reviewed-by and Tested-by tags to patch 1/4.
- Add Laxman's Acked-by tag to patch 2/4.
- Mention in commit message that an unneeded check for match is removed.
- Add Laxman's Acked-by tag to patch 3/4.
- Add Krzysztof's Reviewed-by and Tested-by tags to patch 3/4.
- Add Laxman's Acked-by tag to patch 4/4.
- Add Krzysztof's Reviewed-by and Tested-by tags to patch 4/4.

Javier Martinez Canillas (4):
  mfd: max77686: Don't attempt to get i2c_device_id .data
  mfd: max77686: Use of_device_get_match_data() helper
  mfd: max77686: Use the struct i2c_driver .probe_new instead of .probe
  mfd: max77686: Remove I2C device ID table

In reply to#1558409
If a driver is only used in DT platforms, there's no need to get the
i2c_device_id as an argument of the probe function. Since this data
can be get from the matching of_device_id.

There's a temporary .probe_new field in struct i2c_driver that can be
used as probe callback for the case when i2c_device_id won't be used.
