The patch titled
rtc-at32ap700x: fix irq init oops
has been removed from the -mm tree. Its filename was
rtc-at32ap700x-fix-irq-init-oops.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: rtc-at32ap700x: fix irq init oops
From: David Brownell <[EMAIL PROTECTED]>
Reorder at32_rtc_probe() so that it's safe (no oopsing) to fire the
IRQ handler the instant that it's registered. (Bug noted via "Debug
shared IRQ handlers" kernel debug option.)
