Revision bd8733738c5af6114dd15d340b3f8713e9b624c2 authored by Boris Brezillon on 08 February 2015, 18:23:42 UTC, committed by Linus Walleij on 18 March 2015, 01:01:36 UTC
The gpiochip_lock_as_irq call can fail and return an error,
while the irq_startup is not expected to fail (returns an
unsigned int which is not checked by irq core code).

irq_request/release_resources functions have been created
to address this problem.

Move gpiochip_lock/unlock_as_irq calls into
irq_request/release_resources functions to prevent using a
gpio as an irq if the gpiochip_lock_as_irq call failed.

/sys/module/acpi/parameters/:

trace_method_name
	The AML method name that the user wants to trace

trace_debug_layer
	The temporary debug_layer used when tracing the method.
	Using 0xffffffff by default if it is 0.

trace_debug_level
	The temporary debug_level used when tracing the method.
	Using 0x00ffffff by default if it is 0.

trace_state
	The status of the tracing feature.

	"enabled" means this feature is enabled
	and the AML method is traced every time it's executed.

	"1" means this feature is enabled and the AML method
	will only be traced during the next execution.

	"disabled" means this feature is disabled.
	Users can enable/disable this debug tracing feature by
	"echo string > /sys/module/acpi/parameters/trace_state".
	"string" should be one of "enable", "disable" and "1".
