Merge tag 'regulator-fix-v5.4-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator fixes from Mark Brown: "There are a few core fixes here around error handling and handling if suspend mode configuration and some driver specific fixes here but the most important change is the fix to the fixed-regulator DT schema conversion introduced during the last merge window. That fixes one of the last two errors preventing successful execution of "make dt_binding_check" which will be enormously helpful for DT schema development" * tag 'regulator-fix-v5.4-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: regulator: qcom-rpmh: Fix PMIC5 BoB min voltage regulator: pfuze100-regulator: Variable "val" in pfuze100_regulator_probe() could be uninitialized regulator: lochnagar: Add on_off_delay for VDDCORE regulator: ti-abb: Fix timeout in ti_abb_wait_txdone/ti_abb_clear_all_txdone regulator: da9062: fix suspend_enable/disable preparation dt-bindings: fixed-regulator: fix compatible enum regulator: fixed: Prevent NULL pointer dereference when !CONFIG_OF regulator: core: make regulator_register() EPROBE_DEFER aware regulator: of: fix suspend-min/max-voltage parsing
