Hello,=20
This patch (1/2) brings the sound/oss/trident.c driver up to date with
the driver in the 2.4-ac tree. It fixes the following bugs:=20
* fix wrong cast in suspend/resume (Eric Lemar via Ian Soboroff)
* fix bug where we would free with free_pages() memory allocated via
pci_alloc_consistent().=20
* add a missing unlock on an error path.=20
* rewrite the code to read/write registers of audio codecs for Ali5451
(Lei Hu)
It also does various cleanups so that the code conforms to
Documentation/CodingStyle and is nicer to work with.=20
Patch is against 2.5.29 (latest bitkeeper), compiled and
tested. Please apply.=20
