regulator: lp8755: 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.

d42797a416 regulator: lp8755: constify regulator_ops structure
Declare regulator_ops structure as const as it is only stored in the ops
field of a regulator_desc structure. This field is of type const, so
regulator_ops structures having this property can be made const too.

5713525035 regulator: lp8755: Use devm_regulator_register
This patch moves data allocated using regulator_register to
devm_regulator_register and does away with the calls to
regulator_unregister. Also some labels are removed and a new labelerr is
introduced which is less specific to context.

1586bb4a92 regulator: Remove unnecessary include of linux/delay.h from regulator drivers
All the drivers that need delay for the regulator voltage output voltage to
stabilize after being enabled or after being set to a new value has been
converted to implement enable_time and set_voltage_time_sel callbacks.
Then regulator core will take care of the necessary delay.

This patch removes the unneeded include of linux/delay.h in regulator drivers.

a1a41ab4e9 regulator: lp8755: Fix lp8755_regulator_init unwind code
It's safe to pass NULL argument to regulator_unregister(), so we can remove
the NULL checking before calling regulator_unregister().
However pass a ERR_PTR to regulator_unregister() is wrong, so we need to
explicitly set "pchip->rdev[buck_num] = NULL" before goto err_buck.

This patch also includes below cleanups:
Show correct regulator id in dev_err.
Remove __devexit_p.

several unsed variables were deleted and then test was done.

LP8755 :
The LP8755 is a high performance power management unit.It contains
six step-down DC-DC converters which can can be filexibly bundled
together in multiphase converters as required by application.
