Subject: jazzsonic: free irq if sonic_open() fails
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=62cd69a10683bd17a2454213b8c36a4399c533ab;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.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.
