[PATCH] sound/oss/trident.c [1/2] merge driver from 2.4-ac 

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:

* 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().

* add a missing unlock on an error path.

* 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.

* Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
*
* History
* v0.14.10f
* July 24 2002 Muli Ben-Yehuda <mulix@actcom.co.il>
* patch from Eric Lemar (via Ian Soboroff): in suspend and resume,
* fix wrong cast from pci_dev* to struct trident_card*.
* v0.14.10e
* July 19 2002 Muli Ben-Yehuda <mulix@actcom.co.il>
* rewrite the DMA buffer allocation/deallcoation functions, to make it
* modular and fix a bug where we would call free_pages on memory
* obtained with pci_alloc_consistent. Also remove unnecessary #ifdef
* CONFIG_PROC_FS and various other cleanups.
* v0.14.10d
* July 19 2002 Muli Ben-Yehuda <mulix@actcom.co.il>
* made several printk(KERN_NOTICE...) into TRDBG(...), to avoid spamming
* my syslog with hundreds of messages.
* v0.14.10c
* July 16 2002 Muli Ben-Yehuda <mulix@actcom.co.il>
* Cleaned up Lei Hu's 0.4.10 driver to conform to Documentation/CodingStyle
* and the coding style used in the rest of the file.
* v0.14.10b
* June 23 2002 Muli Ben-Yehuda <mulix@actcom.co.il>
* add a missing unlock_set_fmt, remove a superflous lock/unlock pair
* with nothing in between.
* v0.14.10a
* June 21 2002 Muli Ben-Yehuda <mulix@actcom.co.il>
* use a debug macro instead of #ifdef CONFIG_DEBUG, trim to 80 columns
* per line, use 'do {} while (0)' in statement macros.
* v0.14.10
* June 6 2002 Lei Hu <Lei_hu@ali.com.tw>
* rewrite the part to read/write registers of audio codec for Ali5451
* v0.14.9e
* January 2 2002 Vojtech Pavlik <vojtech@ucw.cz> added gameport
* support to avoid resource conflict with pcigame.c
