Modules: au88x0 driver Removed all use of __devinit/__devexit and init.h from headers. Any attributes given in the prototype but not in the function definition have been moved to the definition. An exception is vortex_eq_free: I removed the __devexit attribute because vortex_eq_free is called from vortex_core_shutdown, and vortex_core_shutdown may be called from __devinit snd_vortex_create. Compile tested with allyesconfig and allmodconfig. Signed-off-by: Dale Sedivec <dale@codefu.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
