regulator: dummy: Use devm_regulator_register()

2021-09-27T12:01:20+00:00

debugfs code complained at boot time that

  debugfs: Directory 'reg-dummy-regulator-dummy' with parent 'regulator'
  already present!

if we compile kernel with DEBUG_TEST_DRIVER_REMOVE. The problem is that we
don't provide .remove() method for dummy_regulator_driver, which should
invoke regulator_unregister() on device teardown to properly free things.

Though it's harmless as dummy_pdev never gets unbound in practice, let's
use devm_regulator_register() to get rid of the inconsistency.

regulator: dummy: Constify dummy_initdata and dummy_ops

2020-09-14T13:24:36+00:00

The only usage of dummy_initdata is to assign its address to the
init_data field of the regulator_config struct and the only usage
dummy_ops is to assign its address to the ops field in the
regulator_desc struct, both which are const pointers. Make them const to
allow the compiler to put them in read-only memory.

Merge tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2014-12-15T00:10:09+00:00

Pull driver core update from Greg KH:
 "Here's the set of driver core patches for 3.19-rc1.

  They are dominated by the removal of the .owner field in platform
  drivers.  They touch a lot of files, but they are "simple" changes,
  just removing a line in a structure.

  Other than that, a few minor driver core and debugfs changes.  There
  are some ath9k patches coming in through this tree that have been
  acked by the wireless maintainers as they relied on the debugfs
  changes.

  Everything has been in linux-next for a while"

regulator: drop owner assignment from platform_drivers

A platform_driver does not need to set an owner, it will be populated by the

regulator: make the dummy regulator's print_constraint more helpful

2012-08-08T13:31:53+00:00

This prevents the output of just

	dummy:

in the boot log. Now it says:

	regulator-dummy: no parameters

which at least doesn't make it look like an accidental printk and also doesn't
only use "dummy" which could mean anything.
