As I got some complaints that the patch was difficult to apply, here it
is again, against 2.5.31-bk6.
Changes from the version yesterday include:
- conversion of usbmouse.c driver by Pat Mochel
- tried to fix up module locking issues in the new_probe() and
new_disco() calls.
I'm pretty sure I've messed up the disconnect and connect ability of
usbfs (the ioctl calls). If anyone can test this out, I would
appreciate it.
thanks,
greg k-h
