Subject: [PATCH RT 2/6] mmci: Remove bogus local_irq_save()
Date: Wed, 06 Feb 2013 17:02:12 -0500 [thread overview]
Message-ID: <20130206220250.964412643@goodmis.org> (raw)
In-Reply-To: 20130206220210.823160521@goodmis.org
[-- Attachment #1: 0002-mmci-Remove-bogus-local_irq_save.patch --]
[-- Type: text/plain, Size: 1243 bytes --]
From: Thomas Gleixner <tglx@linutronix.de>
On !RT interrupt runs with interrupts disabled. On RT it's in a
thread, so no need to disable interrupts at all.
