Subject: [PATCH 5.4 086/408] hwmon: (pmbus/max34440) Fix status register reads for MAX344{51,60,61}

From: Guenter Roeck <linux@...ck-us.net>

[ Upstream commit 6c094b31ea2ad773824362ba0fccb88d36f8d32d ]

Starting with MAX34451, the chips of this series support STATUS_IOUT and
STATUS_TEMPERATURE commands, and no longer report over-current and
over-temperature status with STATUS_MFR_SPECIFIC.

Fixes: 7a001dbab4ade ("hwmon: (pmbus/max34440) Add support for MAX34451.")
Fixes: 50115ac9b6f35 ("hwmon: (pmbus/max34440) Add support for MAX34460 and MAX34461")
