regulator: fan53555: Clean up unneeded fields from struct fan53555_device_info
The *regmap and *rdev can be replaced by local variables.
The slew_rate is no longer used since commit dd7e71fbee
("regulator: fan53555: use set_ramp_delay to set the ramp up slew rate").

regulator: ltc3589: Get rid of struct ltc3589_regulator
After converting to use simplified DT parsing, the struct ltc3589_regulator
only has a desc member. So let's remove struct ltc3589_regulator and use
struct regulator_desc instead.

regulator: core: Actually put the gpiod after use
I went to great lengths to hand over the management of the GPIO
descriptors to the regulator core, and some stray rebased
oneliner in the old patch must have been assuming the devices
were still doing devres management of it.

We handed the management over to the regulator core, so of
course the regulator core shall issue gpiod_put() when done.

Sorry for the descriptor leak.

regulator: core: Avoid potential deadlock on regulator_unregister
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.

regulator: axp20x: Mark expected switch fall-throughs
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warnings:

drivers/regulator/axp20x-regulator.c: In function ‘axp20x_set_dcdc_freq’:
drivers/regulator/axp20x-regulator.c:1023:7: warning: this statement may fall through [-Wimplicit-fallthrough=]

   reg = AXP806_DCDC_MODE_CTRL2;
drivers/regulator/axp20x-regulator.c:1121:2: note: here
  case AXP221_ID:
  ^~~~

Notice that in this particular case, I moved the whole comment
"Fall through to the check below.", which contains the "Fall through"
comment, at the bottom of the case, which is what GCC is expecting
to find.

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.

regulator: core: fix error path for regulator_set_voltage_unlocked
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.

regulator: core: Fix application of "drop lockdep annotation in 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 e5e21f70bf ("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.

regulator: ltc3589: Fix notifier mutex lock warning
The mutex for the regulator_dev must be controlled by the caller of
the regulator_notifier_call_chain(), as described in the comment
for that function.

Failure to mutex lock and unlock surrounding the notifier call results
in a kernel WARN_ON_ONCE() which will dump a backtrace for the
regulator_notifier_call_chain() when that function call is first made.
The mutex can be controlled using the regulator_lock/unlock() API.

regulator: da9062: Use struct_size() in devm_kzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

size = sizeof(struct foo) + count * sizeof(struct boo);
instance = alloc(size, GFP_KERNEL)

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = alloc(struct_size(instance, entry, count), GFP_KERNEL)

Notice that, in this case, variable size is not necessary, hence it is
removed.

regulator: fan53555: Add support for FAN53526
The FAN53526 differs from the FAN53555 only in that the mode bit in
VSEL0/VSEL1 is moved to the CONTROL register, the voltage selector mask
is extended by 1 bit and the step is different.

So extend the existing fan53555 driver to support FAN53526 as well.

regulator: twl6030: Use regulator_list_voltage_linear_range for twl6030ldo_ops
Use linear range to replace the twl6030ldo_list_voltage implementation.
With this change, the min_mV is not used and can be removed from
struct twlreg_info.
