      ALSA: sound/pci/pcxhr/pcxhr.c: introduce missing kfree and pci_disable_device · d6f35e3f
      由 Julia Lawall 提交于 
      Error handling code following a kzalloc should free the allocated data.
The error handling code is adjusted to call pci_disable_device(pci); as
well, as done later in the function

The semantic match that finds the problem is as follows:
