regulator: Use container_of_const() when all types are
Merge series from Krzysztof Kozlowski <krzysztof.kozlowski@oss.qualcomm.com>: Use container_of_const(), which is preferred over container_of(), when the argument 'ptr' and returned pointer are already const, for better code safety and readability. Some drivers already have const everywhere, so container_of_const can be directly used. In few other drivers, the final pointer can be constified that way.

PF1550 PMIC provides battery charging and power supply for low power IoT and
|
||||||
|
wearable applications. This device consists of an i2c controlled MFD that
|
||||||
|
includes regulators, battery charging and an onkey/power button.

Say yes here to add support for NXP PF1550. This is a companion Power
|
||||||
|
Management IC with regulators, onkey, and charger control on chip.
|
||||||
|
This driver provides common support for accessing the device;
|
||||||
|
additional drivers must be enabled in order to use the functionality
|
||||||
|
of the device.
|
||||||
|
|
||||||
|
This driver can also be built as a module and if so will be called
|
||||||
|
pf1550.
