Subject: jazzsonic: free irq if sonic_open() fails
X-Git-Tag: v2.6.36-rc1~571^2~257
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=62cd69a10683bd17a2454213b8c36a4399c533ab;p=profile%2Fcommon%2Fkernel-common.git

jazzsonic: free irq if sonic_open() fails

jazzsonic_open() doesn't check sonic_open() return code. If it is error
we must free requested IRQ.
