Merge tag 'hwmon-for-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging
Pull hwmon updates from Guenter Roeck:
"New drivers:
- Driver for MAX31760 fan speed controller
- Driver for TEXAS TPS546D24 Buck Converter
- Driver for EMC2301/2/3/5 RPM-based PWM Fan Speed Controller
Removed drivers:
- Drop obsolete asus_wmi_ec_sensors driver
Cleanups, affecting various drivers:
- Use DEFINE_SIMPLE_DEV_PM_OPS where appropriate
- Remove forward declarations
- Move from strlcpy with unused retval to strscpy
- Make use of devm_clk_get_enabled()
- Drop devm_of_pwm_get()
Other notable cleanup and improvements:
- Support for additional USB devide ID and support for reporting of
rail mode via debugfs added to corsair-psu driver
- Support for aditional USB ID in nzxt-smart2 driver
- Support for Aquacomputer High Flow Next in aquacomputer_d5next
driver
- Major cleanup of pwm-fan driver
- Major cleanup of mr75203 driver, and added support for new device
revision
And various other minor fixes and cleanups"
