Subject: pinctrl: qcom: Don't clear status bit on irq_unmask

From: Bjorn Andersson <[email protected]>

commit a6566710adaa4a7dd5e0d99820ff9c9c30ee5951 upstream.

Clearing the status bit on irq_unmask will discard any pending interrupt that did arrive after the irq_ack, i.e. while the IRQ handler function was executing.
