2019-05-03regulator: core: simplify return value on suported_voltageJorge Ramirez-Ortiz1-2/+2
All the current clients of this API assume that 0 corresponds to a failure and non-zero to a pass therefore ignoring the need to handle a negative error code. This commit modifies the API to follow that standard since returning a negative (EINVAL) doesn't seem to provide enough value to justify the need to handle it.

2019-04-25regulator: core: Actually put the gpiod after useLinus Walleij1-0/+1
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.
