From ca79408986bf250c22f3130c333787ec44c4d103 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sun, 8 May 2016 00:34:14 +0200 Subject: [PATCH] can: ifi: Treat CAN_CTRLMODE_FD_NON_ISO correctly The CAN_CTRLMODE_FD flag is set for both ISO and BOSCH CANFD mode, while the CAN_CTRLMODE_FD_NON_ISO is additional flag which is only set for CANFD-BOSCH mode. Fix the handling of the flags to reflect this.
