Merge tag 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging
Pull hwmon updates from Guenter Roeck: - New drivers for MAX6697 and compatibles and for INA209. - Added support for IT8771E, IT8772E, MAX34460, MAX34461, MCP98244, and ADT7420 to existing drivers. - Added support for additional attributes to various drivers. - Replaced SENSORS_LIMIT with clamp_val; retire SENSORS_LIMIT; - Clean up PMBus code to reduce its size; clean up adt7410 driver. - A couple of minor bug fixes as well as documentation cleanup. - Out-of-tree change: Replace SENSORS_LIMIT with clamp_val in platform/x86/eeepc-laptop driver. * tag 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging: (32 commits) hwmon: (ntc_thermistor): Fix sparse warnings hwmon: (adt7410) Add device table entry for the adt7420 hwmon: (adt7410) Use I2C_ADDRS helper macro hwmon: (adt7410) Use the SIMPLE_DEV_PM_OPS helper macro hwmon: (adt7410) Let suspend/resume depend on CONFIG_PM_SLEEP hwmon: (adt7410) Clear unwanted bits in the config register hwmon: (jc42) Add support for MCP98244 hwmon: (pmbus) Clean up for code size reduction hwmon: (pmbus/max34440) Add support for MAX34460 and MAX34461 hwmon: (pmbus) Add support for word status register hwmon: (pmbus/zl6100) Add support for VMON/VDRV hwmon: (pmbus) Add function to clear sensor cache hwmon: (pmbus) Add support for additional voltage sensor hwmon: (pmbus) Use krealloc to allocate attribute memory hwmon: (pmbus) Simplify memory allocation for sensor attributes hwmon: (pmbus) Improve boolean handling hwmon: (pmbus) Simplify memory allocation for labels and booleans hwmon: (pmbus) Use dev variable to represent client->dev hwmon: (pmbus) Fix 'Macros with multiple statements' checkpatch error hwmon: (pmbus) Drop unnecessary error messages in probe error path ...
