[PATCH] Initio 9100-U SCSI Driver. ini9100u.c ini9100u.h [KERNEL 2.5.50]

[Aaron Baxter <abaxter@southernohio.net>]

Upon receiving compile errors when using the Initio 9100-U drivers I was able 
to modify and apply 2 patches from the list as well as added a few extra 
lines. I sent this to linux-scsi several days ago and received not complaints 
or comments.

This patch works great with my system, however I do get one odd compile 
warning during make install. It is as follows: No module initio found for 
kernel 2.5.50 This only occurs when the driver is built-in to the kernel. I 
know it's occurring during the mke2fs command, but I was unable to track down 
problem.

I'm unsure who is responsible for maintain this driver but I've seldom seen 
manufactures support beta OSes. If someone could look into this it would be 
great (or maybe someone already fixed it). I would appreciate any feedback I 
could get as I would like to have this contributed to the kernel package (if 
needed).
