2012-09-23hwmon: (via-cputemp) Convert to use devm_ functionsGuenter Roeck1-16/+7
Convert to use devm_ functions to reduce code size and simplify the code. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2012-09-23hwmon: (via-cputemp) Use get_online_cpus to avoid races involving CPU hotplugSilas Boyd-Wickizer1-0/+5
via_cputemp_init loops with for_each_online_cpu, adding platform_devices, then calls register_hotcpu_notifier. If a CPU is offlined between the loop and register_hotcpu_notifier, then later onlined, via_cputemp_device_add will attempt to add platform devices with the same ID. A similar race occurs during via_cputemp_exit, after the module calls unregister_hotcpu_notifier, a CPU might offline and a device will exist for a CPU that is offline. This fix surrounds for_each_online_cpu and register_hotcpu_notifier with get_online_cpus+put_online_cpus; and surrounds unregister_hotcpu_notifier and device unregistering with get_online_cpus+put_online_cpus. Build tested. Signed-off-by: Silas Boyd-Wickizer <sbw@mit.edu> Acked-by: Harald Welte <laforge@gnumonks.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>

2011-07-25hwmon: (via-cputemp) Add VID reporting supportJean Delvare1-5/+39
At least VIA family 6 model D CPU report the VID settings in a MSR, so expose the value to user-space. Not sure about model A. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Guenter Roeck <guenter.roeck@ericsson.com> Tested-by: Jeff Rickman <jrickman@myamigos.us>

2010-10-25hwmon: ({core, pkg, via-cpu}temp) remove unnecessary CONFIG_HOTPLUG_CPU ifdefsChen Gong1-6/+1
CONFIG_HOTPLUG_CPU is used too much in some drivers. This patch clean them up. Signed-off-by: Chen Gong <gong.chen@linux.intel.com> Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com>

2010-08-14hwmon: (via-cputemp) Remove bogus "SHOW" global variableH. Peter Anvin1-1/+1
The via-cputemp hwmon driver was probably intending "typedef enum { ... } SHOW;", but the "typedef" was missing creating a global variable named "SHOW". There is absolutely no reason to have this in the global namespace. Signed-off-by: H.
