ACPI / PM: Fix unused function warnings for CONFIG_PM_SLEEP

2012-08-10T11:35:32Z

According to compiler warnings, several suspend/resume functions in ACPI drivers are not used for CONFIG_PM_SLEEP unset, so add #ifdefs to prevent them from being built in that case. Signed-off-by: Rafael J. Wysocki

ACPI: Use struct dev_pm_ops for power management in the fan driver

2012-07-01T11:30:59Z

Make the ACPI fan driver define its PM callbacks through a struct dev_pm_ops object rather than by using legacy PM hooks in struct acpi_device_ops. Signed-off-by: Rafael J. Wysocki

ACPI / PM: Drop pm_message_t argument from device suspend callback

2012-07-01T11:30:58Z

None of the drivers implementing the ACPI device suspend callback uses the pm_message_t argument of it, so this argument may be dropped entirely from that callback. This will simplify switching the ACPI bus type to PM handling based on struct dev_pm_ops. Signed-off-by: Rafael J. Wysocki

ACPI: constify ops structs

2011-07-16T22:36:17Z

Structs battery_file, acpi_dock_ops, file_operations, thermal_cooling_device_ops, thermal_zone_device_ops, kernel_param_ops are not changed in runtime. It is safe to make them const. register_hotplug_dock_device() was altered to take const "ops" argument to respect acpi_dock_ops' const notion.

ACPI / Fan: Rework the handling of power resources

2011-01-12T09:48:45Z

Use the new function acpi_bus_update_power() for manipulating power resources used by ACPI fan devices, which allows them to be put into the right state during initialization and resume. Consequently, remove the flags.force_power_state field from struct acpi_device, which is not necessary any more. Signed-off-by: Rafael J. Wysocki Signed-off-by: Len Brown

ACPI fan: remove deprecated procfs I/F

2010-10-16T02:02:47Z

Remove deprecated ACPI Fan driver procfs interface. The ACPI fan driver (CONFIG_ACPI_FAN) selects the generic thermal sysfs driver (CONFIG_THERMAL) since 2.6.26, so new sysfs I/F is available at /sys/class/thermal/cooling_devicecX/ Signed-off-by: Zhang Rui Signed-off-by: Len Brown

ACPI: fan: Fix more unbalanced code block

2010-09-29T18:08:10Z

commit 934231de706d2579fae14f5857fcd8de991009ff fixes an unbalanced CONFIG_ACPI_PROCFS code block during module initialisation. This patch fixes similar issue but for the module exit. Signed-off-by: Luis Henriques Signed-off-by: Len Brown

ACPI: fan: fix unbalanced code block

2010-06-10T15:24:51Z

The code block braced with CONFIG_ACPI_PROCFS is unblanced. When CONFIG_ACPI_PROCFS=n, kernel trace will be produced like: Call Trace: [] ? remove_proc_entry+0x20d/0x290 [] ? remove_proc_entry+0x20d/0x290 [] warn_slowpath_common+0x6c/0xc0 [] ? remove_proc_entry+0x20d/0x290 [] warn_slowpath_fmt+0x26/0x30 [] remove_proc_entry+0x20d/0x290 [] ? proc_register+0x117/0x1f0 [] ? proc_mkdir_mode+0x33/0x50 [] ? acpi_fan_init+0x0/0x2c [] acpi_fan_init+0x23/0x2c [] do_one_initcall+0x23/0x180 [] ? init_irq_proc+0x67/0x80 [] kernel_init+0x13c/0x20e [] ? schedule_tail+0x20/0x90 [] ? syscall_exit+0x5/0x16 [] ? kernel_init+0x0/0x20e [] ? kernel_init+0x0/0x20e [] kernel_thread_helper+0x6/0x30 ---[ end trace a7919e7f17c0a725 ]--- Then also bracket later error checking code with ACPI_PROCFS option to avoid mismatch problem.

ACPI: Move definition of PREFIX from acpi_bus.h to internal..h

2009-08-28T23:57:27Z

Linux/ACPI core files using internal.h all PREFIX "ACPI: ", however, not all ACPI drivers use/want it -- and they should not have to #undef PREFIX to define their own. Add GPL commment to internal.h while we are there. This does not change any actual console output, asside from a whitespace fix. Signed-off-by: Len Brown
