From 8880f2cbdb0a981ea8e6a5ce2915abac26120523 Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Sun, 24 Aug 2014 19:27:43 -0300 Subject: [PATCH] [media] airspy: remove unneeded spinlock irq flags initialization There is no need to init flags before calling spin_lock_irqsave(). spin_lock_irqsave is a macro which stores value to 'flags'.
