[ 02/77] ALSA: bt87x: Make load_all parameter working again

From: Greg Kroah-Hartman
Date: Fri Mar 01 2013 - 14:45:21 EST


3.8-stable review patch. If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <tiwai@xxxxxxx>

commit aacfddfdadb3540651d263245069631f341e953a upstream.

Along with a clean up commit [e9f66d9b9: ALSA: pci: clean up using
module_pci_driver()], bt87x driver lost the functionality of load_all
parameter. This patch does a partial revert of the commit only for
bt87x.c to recover it.
