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.

510799eaba regulator: lp8755: Remove enum bucks
We already have enum lp8755_bucks in lp8755.h, so it looks pointless adding
enum bucks in lp8755.c.

cad877ef0a regulator: lp8755: Fix mask for pchip->mphase
According to the datasheet, it has 9 multi-phase mode from 0 to 8 and it takes
4 bits in the register.
The mask for pchip->mphase should be 0x0F.

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.

This patch is for new lp8755 regulator dirver and
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.
