Subject: [PATCH] greybus: beagleplay: select CONFIG_CRC_CCITT

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

Without the CRC_CCITT code, the new greybus driver fails to link:

aarch64-linux-ld: drivers/greybus/gb-beagleplay.o: in function `hdlc_append_tx_u8':
gb-beagleplay.c:(.text+0x158): undefined reference to `crc_ccitt'
aarch64-linux-ld: drivers/greybus/gb-beagleplay.o: in function `gb_tty_receive':
gb-beagleplay.c:(.text+0x5c4): undefined reference to `crc_ccitt'
