Subject: [media] airspy: remove unneeded spinlock irq flags initialization
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8880f2cbdb0a981ea8e6a5ce2915abac26120523;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[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'.
