These fields are only used in anatop_regulator_probe() so use local variables instead. The *initdata is not used so can be removed. The *anatop is renamed to *regmap for better readability.

2019-04-05regulator: core: Avoid potential deadlock on regulator_unregisterCharles Keepax
Lockdep reports the following issue on my setup: Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock((work_completion)(&(&rdev->disable_work)->work)); lock(regulator_list_mutex); lock((work_completion)(&(&rdev->disable_work)->work)); lock(regulator_list_mutex); The problem is that regulator_unregister takes the regulator_list_mutex and then calls flush_work on disable_work. But regulator_disable_work calls regulator_lock_dependent which will also take the regulator_list_mutex. Resulting in a deadlock if the flush_work call actually needs to flush the work. Fix this issue by moving the flush_work outside of the regulator_list_mutex. The list mutex is not used to guard the point at which the delayed work is queued, so its use adds no additional safety.

2019-03-19regulator: core: fix error path for regulator_set_voltage_unlockedSteve Twiss
During several error paths in the function regulator_set_voltage_unlocked() the value of 'ret' can take on negative error values. However, in calls that go through the 'goto out' statement, this return value is lost and return 0 is used instead, indicating a 'pass'. There are several cases where this function should legitimately return a fail instead of a pass: one such case includes constraints check during voltage selection in the call to regulator_check_voltage(), which can have -EINVAL for the case when an unsupported voltage is incorrectly requested. In that case, -22 is expected as the return value, not 0.

drms_uA_update()" [The original commit was sent against -next but needed to be sent as a bugfix, however -next had some additional changes which needed to be reverted. Now everything is all in one branch applying the rest of the changes to fix up the merge issue -- broonie] commit e5e21f70bfd3 ("regulator: core: Take lock before applying system load") took the regulator lock before calling drms_uA_update() in order to silence a lockdep warning during regulator_register(). However, we are not supposed to need locks at this point as the regulator is in the process of being registered, so there should be no possibility of concurrent access. Instead, remove the unnecessary locking and simply drop the lockdep annotation, since it is no longer valid.
