| * History |
| * v0.14.10j |
| * January 3 2004 Eugene Teo <eugeneteo@eugeneteo.net> |

| * defined in linux/kernel.h. |
| * v0.14.10i |
| * December 29 2003 Muli Ben-Yehuda <mulix@mulix.org> |
| * major cleanup for 2.6, fix a few error patch buglets |
| * with returning without properly cleaning up first, |
| * get rid of lock_kernel(). |
| * v0.14.10h |
| * Sept 10 2002 Pascal Schmidt <der.eremit@email.de> |
| * added support for ALi 5451 joystick port |
| * v0.14.10g |

| * 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> |

| * 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 |

| * support to avoid resource conflict with pcigame.c |
| * v0.14.9d |
| * October 8 2001 Arnaldo Carvalho de Melo <acme@conectiva.com.br> |
| * use set_current_state, properly release resources on failure in |
| * trident_probe, get rid of check_region |
| * v0.14.9c |
| * August 10 2001 Peter Wächtler <pwaechtler@loewe-komp.de> |

| * this chip is often found in settop boxes (combined video+audio) |
| * v0.14.9b |
| * Switch to static inline not extern inline (gcc 3) |
| * v0.14.9a |
| * Aug 6 2001 Alan Cox |
| * 0.14.9 crashed on rmmod due to a timer/bh left running. Simplified |
| * the existing logic (the BH doesn't help as ac97 is lock_irqsave) |
| * and used del_timer_sync to clean up |
| * Fixed a problem where the ALi change broke my generic card |
| * v0.14.9 |
| * Jul 10 2001 Matt Wu |
