pte_offset_kernel deps for spca5xx

Description

I'm currently using openwrt experimental version release r2730.

It seem like the compilation procedure for spca5xx quite broken for pte_offset_kernel directive. Loading the module will fail.

root@wl500g:~# insmod spca5xx
Using /lib/modules/2.4.32/spca5xx.o
insmod: unresolved symbol pte_offset_kernel

The only solution i found it to load successfully in kernel is by removing "ifdef pte_offset" in source code so that it only use pte_offset instead of pte_offset_kernel.

laptop@spca5xx-20051105 # grep pte_ drivers/usb/*
drivers/usb/spca5xx.c:  pte_t *ptep, pte;
drivers/usb/spca5xx.c:    /* WOLT kernels appear to have changed pte_offset to pte_offset_kernel */
drivers/usb/spca5xx.c:#ifdef pte_offset
drivers/usb/spca5xx.c:    ptep = pte_offset (pmd, adr);
drivers/usb/spca5xx.c:#else /* pte_offset */
drivers/usb/spca5xx.c:    ptep = pte_offset_kernel (pmd, adr);
drivers/usb/spca5xx.c:#endif /* pte_offset */
drivers/usb/spca5xx.c:    if (pte_present (pte))
drivers/usb/spca5xx.c:        ret = (unsigned long) page_address (pte_page (pte));
