Subject: [PATCH 025/182] pinctrl: msm: drop wake_irqs bitmap
|
|
|
|
Currently, the wake_irqs bitmap is used to track whether there are any
|
|
gpio's which are configured as wake irqs, and uses this to determine
|
|
whether or not to call enable_irq_wake()/disable_irq_wake() on the
|
|
summary interrupt.
|
|
|
|
However, the genirq core already handles this case, by maintaining a
|
|
'wake_count' per irq_desc, and only calling into the controlling
|
|
irq_chip when wake_count transitions 0 <-> 1.
|
|
|
|
Drop this bitmap, and unconditionally call irq_set_irq_wake() on the
|
|
summary interrupt.
