Merge branch '2023-08-14-keep-fixed-gpio-regulator-count-in-balance' into next
To quote the author:
The commit 4fcba5d556b4 ("regulator: implement basic reference counter")
have made it more important to keep fixed/gpio regulators enable/disable
state in balance.
This series fixes an inbalance in the mmc_dw driver and changes to use
the more relaxed regulator_set_enable_if_allowed function for a few
other drivers.
The regulator_set_enable_if_allowed function is more relaxed and will
return ENOSYS if the provided regulator is NULL or when DM_REGULATOR
was disabled. Using the following call convention should be safe:
ret = regulator_set_enable_if_allowed(<supply>, <true|false>);
if (ret && ret != -ENOSYS)
return ret;
