===================================================================


ChangeSet@1.984, 2003-01-04 21:22:07+01:00, jochen@ayse.bocc.de
Fixed forgotten strings for rename tmsisa -> skisa.

ChangeSet@1.983, 2003-01-04 21:20:14+01:00, jochen@ayse.bocc.de
New low level tms380 driver for Proteon 1392 / 1392+ cards
(port from existing 2.2 kernel code)

ChangeSet@1.977.2.2, 2003-01-04 09:27:02+01:00, jochen@ayse.bocc.de
RIF fix for tcpdump.

ChangeSet@1.977.2.1, 2003-01-04 09:21:58+01:00, jochen@ayse.bocc.de
- add spinlock to fix race condition in tms380tr.
- fix startup of tmsisa to not register and unregister devices multiple
times, so hotplug doesn't run wild.
- add support for statically compiling tmsisa into kernel.
- remove unnecessary console SPAM during boot.
- fixed probing of ISA devices in tmsisa.
- fixed unsafe reference counting.
- fixed __init function causing Oops with new module system.
- rename tmsisa to skisa.
