ALSA: riptide - proper handling of pci_register_driver for joystick
We need to check returning error for pci_register_driver(&joystick_driver) On failure, we should unregister formerly registered audio drivers This also fixed the compiler warning : CC [M] sound/pci/riptide/riptide.o sound/pci/riptide/riptide.c: In function ‘alsa_card_riptide_init’: sound/pci/riptide/riptide.c:2200: warning: ignoring return value of ‘__pci_register_driver’, declared with attribute warn_unused_result Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
