    vmxnet3: fix lock imbalance in vmxnet3_tq_xmit() · efc21d95
    Arnd Bergmann 提交于
    A recent bug fix rearranged the code in vmxnet3_tq_xmit() in a
    way that left the error handling for oversized headers unlock
    a lock that had not been taken yet. Gcc warns about the incorrect
    use of the 'flags' variable because of that:
    
    drivers/net/vmxnet3/vmxnet3_drv.c: In function 'vmxnet3_tq_xmit.constprop':
    include/linux/spinlock.h:246:3: error: 'flags' may be used uninitialized in this function [-Werror=maybe-uninitialized]
    
    This changes the error handling path to 'goto' the end of the function
    beyond the lock/unlock pair.
