Check the return value of led_classdev_register and unregister all
registered devices, if registering one device fails.  Also the dynamic
memory handling is totally bogus.  You can't allocate multiple chunks via
kzalloc() and expect them to be in order later.  I wonder how this ever
worked.

menuconfig SOUND
	tristate "Sound card support"
	depends on HAS_IOMEM
	help
	  If you have a sound card in your computer, i.e. if it can say more
	  than an occasional beep, say Y.  Be sure to have all the information
	  about your sound card and its configuration down (I/O port,
	  interrupt and DMA channel), because you will be asked for it.

	  You want to read the Sound-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>. General information about
	  the modular sound system is contained in the files
	  <file:Documentation/sound/oss/Introduction>.  The file
	  <file:Documentation/sound/oss/README.OSS> contains some slightly
	  outdated but still useful information as well.  Newer sound
	  driver documentation is found in <file:Documentation/sound/alsa/*>.

	  If you have a PnP sound card and you want to configure it at boot
	  time using the ISA PnP tools (read
	  <http://www.roestock.demon.co.uk/isapnptools/>), then you need to
	  compile the sound card support as a module and load that module
	  after the PnP configuration is finished.  To do this, choose M here
	  and read <file:Documentation/sound/oss/README.modules>; the module
	  will be called soundcore.

	  sound although they're sharing the AC97 bus. Concerned drivers
	  should "select" this.
