USB: dwc3: qcom: fix wakeup after probe deferral
Browse files Browse the repository at this point in the history
commit 41f5a09 upstream.

The Qualcomm glue driver is overriding the interrupt trigger types
defined by firmware when requesting the wakeup interrupts during probe.

This can lead to a failure to map the DP/DM wakeup interrupts after a
probe deferral as the firmware defined trigger types do not match the
type used for the initial mapping:

	irq: type mismatch, failed to map hwirq-14 for interrupt-controller@b220000!
	irq: type mismatch, failed to map hwirq-15 for interrupt-controller@b220000!

Fix this by not overriding the firmware provided trigger types when
requesting the wakeup interrupts.
