[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.  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 
decipher the code enough to find the problem.  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).
