From 2f6e5f9458646263d3d9ffadd5e11e3d8d15a7d0 Mon Sep 17 00:00:00 2001 From: Yong Zhang Date: Fri, 23 Mar 2012 15:02:34 -0700 Subject: drivers/rtc: remove IRQF_DISABLED Since commit e58aa3d2d0cc ("genirq: run irq handlers with interrupts disabled") we run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled - see commit b738a50a2026 ("genirq: warn when handler enables interrupts"). So now this flag is a NOOP and can be removed.
