[PATCH] USB: sisusb[vga] update
here is a new and extended version of the sisusbvga (previously: sisusb)
driver. The patch is against 2.6.13 and updates the driver to version 0.0.8.
Additions include complete VGA/EGA text console support and a build-in
display mode infrastructure for userland applications that don't know
about the graphics internals.
Fixes include some BE/LE issues and a get/put_dev bug in the previous
version.
Other changes include a change of the module name from "sisusb" to
"sisusbvga". The previous one was too generic IMHO.
Please note that the patch also affects the Makefile in
drivers/video/console as the driver requires the VGA 8x16 font in case
the text console part is selected.
Heavily tested, as usual. Please apply.
One thing though: I already prepared for removal of the "mode" field and
the changed "name" field in the usb_class_driver structure. This will
perhaps need some refinement depending on whether you/Linus merge the
respective core changes before or after 2.6.14.
