Subject: [PATCH] hwmon: (pmbus) allow to use a custom read_byte_data function for PMBUS_CAPABILITY
Date: Tue, 19 Apr 2022 21:52:10 +0000 [thread overview]
Message-ID: <20220419215149.309760-1-dev_public@wujek.eu> (raw)
Some devices returns a wrong value in PMBUS_CAPABILITY register.
Allow the use of read_byte_data function defined in a driver for
a specific device.
