1. 2.5.45: drivers/mtd/mtdblock.c won't compile -- misordered declaration

When I compile 2.5.45, I get the following errors:

     v850e-elf-gcc -Wp,-MD,drivers/mtd/.mtdblock.o.d -D__KERNEL__ -Iinclude -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -g -fomit-frame-pointer -fno-strict-aliasing -fno-common -mv850e -ffixed-r16 -mno-prolog-function -fno-builtin -D__linux__ -DUTS_SYSNAME=\"uClinux\" -nostdinc -iwithprefix include    -DKBUILD_BASENAME=mtdblock   -c -o drivers/mtd/mtdblock.o drivers/mtd/mtdblock.c
   drivers/mtd/mtdblock.c:398: parse error before `struct'
   drivers/mtd/mtdblock.c:399: `p' undeclared (first use in this function)

I fixed this locally as follows:

diff -ruN -X../cludes ../orig/linux-2.5.45-uc1/drivers/mtd/mtdblock.c drivers/mtd/mtdblock.c
--- ../orig/linux-2.5.45-uc1/drivers/mtd/mtdblock.c     2002-10-31 11:41:04.000000000 +0900

        unsigned int res;

        while (!blk_queue_empty(&mtd_queue)) {
+               struct mtdblk_dev **p;
                struct request *req = elv_next_request(&mtd_queue);
                spin_unlock_irq(mtd_queue.queue_lock);
-               struct mtdblk_dev **p = req->rq_disk->private_data;
+               p = req->rq_disk->private_data;
                mtdblk = *p;
                res = 0;

Thanks,

-Miles
