H A Dmp2975.cdiff c7506a2b5a8233c32bd05353aac7c7b3af05d85f Mon Mar 18 18:44:05 CET 2024 Patrick Rudolph <patrick.rudolph@9elements.com> hwmon: (pmbus/mp2975) Fix IRQ masking

The MP2971/MP2973 use a custom 16bit register format for
SMBALERT_MASK which doesn't follow the PMBUS specification.

Map the PMBUS defined bits used by the common code onto the custom
format used by MPS and since the SMBALERT_MASK is currently never read
by common code only implement the mapping for write transactions.
