[2.4 patch] fix two pcmcia/cardbus.c compile warnings

[Adrian Bunk]

I got the following compile warnings in 2.4.24-pre1:

<--  snip  -->

...
gcc -D__KERNEL__ -I/tmp/linux-2.4.24-pre1/include -Wall 
-Wstrict-prototypes -Wn\
o-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer 
-pipe -mp\
referred-stack-boundary=2 -march=i686   -nostdinc -iwithprefix include 
-DKBUILD\
_BASENAME=cardbus  -c -o cardbus.o cardbus.c
cardbus.c: In function `cb_scan_slot':
...
cardbus.c:226: warning: unused variable `bus'
cardbus.c: In function `program_bridge':
cardbus.c:405: warning: control reaches end of non-void function
...

<--  snip  -->

The patch below does the following:
- remove the unused variable
- make the function without return void (the only caller doesn't check
  the return value)


Please apply
Adrian
