sound/pci/riptide/riptide.c compiler warning

[Jaswinder Singh Rajput]

I am getting this compiler warning in linus tree :

  CC [M]  sound/pci/riptide/riptide.o
sound/pci/riptide/riptide.c: In function âalsa_card_riptide_initâ:
sound/pci/riptide/riptide.c:2200: warning: ignoring return value of â__pci_register_driverâ, declared with attribute warn_unused_result

This fixes the warning in my case, hope this will be helpful :

diff --git a/sound/pci/riptide/riptide.c b/sound/pci/riptide/riptide.c
