Fix pm8941-misc extcon interrupt dependency assumptions

[PATCH v4 2/2 RESEND] extcon: qcom-spmi: Switch to platform_get_irq_byname_optional

Posted by Bryan O'Donoghue 2 years, 8 months ago

Valid configurations for the extcon interrupt declarations are

- usb_id
- usb_vbus
- (usb_id | usb_vbus)

In the case of a standalone usb_id or usb_vbus failure to find one of the
interrupts shouldn't generate a warning message. A warning is already in
place if both IRQs are missing.

Switch to using platform_get_irq_byname_optional() in order to facilitate
this behaviour.

Applied it. Thanks.
