Stanislav Fomichev 6b99e3569b platform/x86: thinkpad_acpi: Fix warning about deprecated hwmon_device_register ... Use hwmon_device_register_with_groups instead of deprecated hwmon_device_register and fix a dmesg warning. This patch however changes the userspace API. hwmon_device_register_with_groups takes `hwmon' name as an argument and creates a name file in the `hwmon' device, not in the `platform_device'. This allows us to remove custom `name' device attribute, but in order to make lm-sensors happy we also have to move fans and thermal attributes to the `hwmon' device. Even though this patch changes userspace API, it's still compatible with the lm-sensors. Starting with lm-sensors 3.0 (circa 2007), it looks at both hwmon and the backing device for the name and other attributes. before: $ cat /sys/devices/platform/thinkpad_hwmon/{name,fan1_input} thinkpad 2007 $ cat /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon1/{name,fan1_input} cat: /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon1/name: No such file or directory cat: /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon1/fan1_input: No such file or directory $ cat /sys/class/hwmon/hwmon1/{name,fan1_input} cat: /sys/class/hwmon/hwmon1/name: No such file or directory cat: /sys/class/hwmon/hwmon1/fan1_input: No such file or directory $ sensors thinkpad-isa-0000 Adapter: ISA adapter fan1: 3533 RPM after: $ cat /sys/devices/platform/thinkpad_hwmon/{name,fan1_input} cat: /sys/devices/platform/thinkpad_hwmon/name: No such file or directory cat: /sys/devices/platform/thinkpad_hwmon/fan1_input: No such file or directory $ cat /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon1/{name,fan1_input} thinkpad 3478 $ cat /sys/class/hwmon/hwmon1/{name,fan1_input} thinkpad 3478 $ sensors thinkpad-isa-0000 Adapter: ISA adapter fan1: 3489 RPM $ sensors -v sensors version 3.4.0 with libsensors version 3.4.0 Signed-off-by: Stanislav Fomichev <kernel@fomichev.me> [dvhart: cleaned up commit log, bumped version to 4.14 in the doc change] Signed-off-by: Darren Hart (VMware) <dvhart@infradead.org>		2017-08-18 15:57:24 -07:00
