hwmon: (pmbus/core) export pmbus_check_and_notify_faults()

Browse source

Factor of pmbus_fault_handler() into an exported helper so
drivers can notify sequence from a polling work item on boards
for which the chip's SMBALERT# pin is not wired to the
CPU. The interrupt handler becomes a thin wrapper.

Like the SMBALERT# path, the helper notifies and then clears the
latched faults unconditionally, so a polling caller inherits exactly
the interrupt semantics.
