Subject: [PATCH 4.9 22/25] wan: ds26522: select CONFIG_BITREVERSE

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

commit 69931e11288520c250152180ecf9b6ac5e6e40ed upstream.

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'
