The dev_err_probe() has (at least) following benefits over dev_err()
when printing an error print for a failed function call at a device
driver probe:
- Omit error level print if error is 'EPRBE_DEFER'
- Standardized print format for returned error
- return the error value allowing shortening calls like:
if (ret) {
dev_err(...);
return ret;
}
to
if (ret)
return dev_err_probe(...);
Convert the ROHM BD71828, ROHM BD71815 and ROHM BD9576 regulator drivers
to use the dev_err_probe() when returned error is not hard-coded constant.

I would like to stop exporting OF-specific devm_gpiod_get_from_of_node()
so that gpiolib can be cleaned a bit, so let's switch to the generic
fwnode property API.

The content of bd71815_regulators is never changed, no need to duplicate
it, thus remove descs[BD71815_REGULATOR_CNT].
The *regmap, *dev and *rdev[BD71815_REGULATOR_CNT] are not really needed.
The *gps is unused.
Thus the struct bd71815_pmic can be removed.

./drivers/regulator/bd71815-regulator.c:644:3-8: No need to set .owner here. The core will do it.
Remove .owner field if calls are used which set it automatically

Support voltage control for regulators on ROHM BD71815 PMIC.
ROHM BD71815 contains 5 bucks, 7 LDOs and a boost (intended for LED).
Bucks 1 and 2 support HW state based voltage level and enable states. Other
regulators support HW state based enable states. All bucks and LDOs 1-5
allow voltage changes for RUN state and LDO4 can be enabled/disabled via
GPIO.
LDO3 does support changing between two predetermined voltages by using
a GPIO but this functionality is not included in this commit.
This work is derived from driver originally written by Tony Luo
<luofc@embedinfo.com> - although not much of original work is left.
