When trying to use the LED GPIO trigger with e.g. the PCA953x GPIO
driver, request_irq() fails with -EINVAL, because the GPIO driver
requires a nested interrupt handler.
Use request_any_context_irq() to be able to use any GPIO driver as LED
trigger.

When trying to use the LED GPIO trigger with e.g. the PCA953x GPIO
driver, request_irq() fails with -EINVAL, because the GPIO driver
requires a nested interrupt handler.
Use request_any_context_irq() to be able to use any GPIO driver as LED
trigger.
