Subject: [PATCH v2] RTC: PXA: Fix regression of interrupt before ioremap

From: [email-masked] (Petr Cvek)
Date: Thu, 29 Jan 2015 12:51:38 +0100

Interrupts appear before register set of the PXA2xx RTC controller is ioremaped.

This fixes regression from:
  'commit a44802f8fb7e593adabc6ef53c8df45a1717fa9b ("drivers/rtc/rtc-pxa.c: fix alarm can't wake up system issue")'
  'commit 2f6e5f9458646263d3d9ffadd5e11e3d8d15a7d0 ("drivers/rtc: remove IRQF_DISABLED")'
