History
Adamski, Krzysztof (Nokia - PL/Wroclaw) 38463721ec hwmon: (pmbus/core) mutex_lock write in pmbus_set_samples 
update_lock is a mutex intended to protect write operations. It was not
taken, however, when _pmbus_write_word_data is called from
pmbus_set_samples() function which may cause problems especially when
some PMBUS_VIRT_* operation is implemented as a read-modify-write cycle.

This patch makes sure the lock is held during the operation.

Fixes: 49c4455dcc ("hwmon: (pmbus) Introduce PMBUS_VIRT_*_SAMPLES registers")
