[PATCH] hwmon: (pmbus_core) Allow to hook PMBUS_SMBALERT_MASK

From: Naresh Solanki
Date: Tue Jan 30 2024 - 10:29:20 EST


From: Patrick Rudolph <patrick.rudolph@xxxxxxxxxxxxx>

Use _pmbus_write_word_data to allow intercepting writes to
PMBUS_SMBALERT_MASK in the custom chip specific code.

This is required for MP2971/MP2973 which doesn't follow the
PMBUS specification for PMBUS_SMBALERT_MASK.
