From b63ab6b064f73721568a46080d41422ea223ee6e Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Sun, 24 Aug 2014 23:26:23 -0300 Subject: [PATCH] [media] msi2500: remove unneeded spinlock irq flags initialization There is no need to init flags before calling spin_lock_irqsave(). spin_lock_irqsave is macro which stores value to 'flags'.
