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;
