Subject: [PATCH 7/7] wan: ds26522: select CONFIG_BITREVERSE

From: Arnd Bergmann <arnd@...db.de>

Without this, the driver runs into a link failure

arm-linux-gnueabi-ld: drivers/net/wan/slic_ds26522.o: in function `slic_ds26522_probe':
slic_ds26522.c:(.text+0x100c): undefined reference to `byte_rev_table'
