2011-07-22ALSA: asihpi - Remove spurious adapter index checkEliot Blennerhassett
Subsystem requests don't have or need a valid adapter index. The adapter index is already checked further on, before it is used to index the adapters array. (Reverts 4a122c10f) Signed-off-by: Eliot Blennerhassett <eblennerhassett@audioscience.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-03-18ALSA: sound/pci/asihpi: check adapter index in hpi_ioctlDan Rosenberg
The user-supplied index into the adapters array needs to be checked, or an out-of-bounds kernel pointer could be accessed and used, leading to potentially exploitable memory corruption.

2011-02-10ALSA: asihpi - Interrelated HPI tidy up.Eliot Blennerhassett
Remove many unused functions. Update some message and cache structs. Use pci info directly from pci_dev.
