pdcraid.o compile warnings + patch?

[Matt Selsky <selsky@xxxxxxxxxxxx>]

I was compiling pdcraid.o as part of 2.4.12-ac6 and I got the following
warnings:

gcc -D__KERNEL__ -I/usr/src/linux-2.4.12-ac6/include -Wall
-Wstrict-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer
-fno-strict-aliasing -fno-common -pipe -mpreferred-stack-boundary=2
-march=i686 -DMODULE -DMODVERSIONS -include
/usr/src/linux-2.4.12-ac6/include/linux/modversions.h   -c -o pdcraid.o
pdcraid.c
pdcraid.c: In function `pdcraid_ioctl':
pdcraid.c:103: warning: unused variable `larg'
pdcraid.c: In function `pdcraid0_make_request':
pdcraid.c:288: warning: label `outerr' defined but not used
pdcraid.c: In function `pdcraid_init_one':
pdcraid.c:554: warning: unused variable `q'
pdcraid.c: In function `pdcraid_init':
pdcraid.c:586: warning: unused variable `i'  

The following patch seems to get rid of most of the warnings:
