Subject: [2.6 patch] SCSI qla2xxx: fix inline compile errors
Trying to compile the SCSI qla2xxx driver in 2.6.8-rc1-mm1 using gcc 3.4
results in the following compile errors:
<-- snip -->
...
CC drivers/scsi/qla2xxx/qla_os.o

make[3]: *** [drivers/scsi/qla2xxx/qla_rscn.o] Error 1
<-- snip -->
The patch below moves some inlined functions above the place where they
are called the first time.
An alternative approach would be to remove the inlines.
