From: Adrian Bunk
Date: Sat Nov 25 2006 - 20:16:19 EST


This patch contains the following possible cleanups:
- make needlessly global functions static
- #if 0 the following unused global functions:
- zd_chip.c: zd_ioread16()
- zd_chip.c: zd_ioread32()
- zd_chip.c: zd_iowrite16()
- zd_chip.c: zd_ioread32v()
- zd_chip.c: zd_read_mac_addr()
- zd_chip.c: zd_set_beacon_interval()
- zd_mac.c: zd_dump_rx_status()
- zd_util.c: zd_hexdump()
