From f3a138c10b9a5f716d2b773e0ae08401ebd19f80 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Thu, 3 May 2012 07:12:48 +0200 Subject: [PATCH] NFC: Select CRC_CCITT for SHDLC link layer of HCI based drivers The SHDLC link layer of HCI based drivers uses CRC-CCITT and thus needs to select that kernel option. Otherwise it ends up with this linking error: net/built-in.o: In function `nfc_shdlc_add_len_crc': net/nfc/hci/shdlc.c:113: undefined reference to `crc_ccitt' Signed-off-by: Marcel Holtmann Acked-by: Samuel Ortiz Signed-off-by: John W.
