2007-10-07Convert snd-page-alloc proc file to use seq_file (CVE-2007-4571)Takashi Iwai
Commit ccec6e2c4a74adf76ed4e2478091a311b1806212 in mainline. Use seq_file for the proc file read/write of snd-page-alloc module. This automatically fixes bugs in the old proc code.

Fix the max number of codecs detected by HD-intel (and compatible) controllers. ATI controllers may have up to 4 codecs while ICH up to 3. Now max codecs is defined according to the driver type, either 3 or 4. Currently 4 is set only to ATI chips. Other might need the same change, too.
