      ALSA: sound/pci/mixart/mixart.c: Add missing snd_card_free · 73f6a12e
      由 Julia Lawall 提交于 
      The function snd_mixart_create creates a link between mgr and card that
allows snd_mixart_free to free card as well.  But if snd_mixart_create
fails, then the link has not been created and card has to be freed explicitly.

The semantic match that finds the problem is as follows:

      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

      [ALSA] Remove sound/driver.h · 9004acc7
      由 Takashi Iwai 提交于 
      This header file exists only for some hacks to adapt alsa-driver
tree.  It's useless for building in the kernel.  Let's move a few
lines in it to sound/core.h and remove it.
With this patch, sound/driver.h isn't removed but has just a single
compile warning to include it.  This should be really killed in
future.
