9f4401ad37 hwmon: (ltc4282) convert from round_rate() to determine_rate() 
The round_rate() clk ops is deprecated, so migrate this driver from
round_rate() to determine_rate() using the Coccinelle semantic patch
appended to the "under-the-cut" portion of the patch.

6e253295e9 hwmon: (ltc4282) fix copy paste on variable name 
The struct hwmon_chip_info was named ltc2947_chip_info which is
obviously a copy paste leftover. Name it accordingly.

c25892b7a1 hwmon: (ltc4282) avoid repeated register write 
The fault enabled bits were being mistankenly enabled twice in case the FW
property is present. Remove one of the writes.

2e522c2933 hwmon: (ltc4282) Use per-client debugfs entry 
The I2C core now offers a debugfs-directory per client. Use it and
remove the custom handling.

cbc29538db hwmon: Add driver for LTC4282 
The LTC4282 hot swap controller allows a board to be safely inserted and
removed from a live backplane. Using one or more external N-channel pass
transistors, board supply voltage and inrush current are ramped up at an
adjustable rate. An I2C interface and onboard ADC allows for monitoring
of board current, voltage, power, energy and fault status.
