From 1114be1e5ca43d465e2da95a2118672f7d4110fb Mon Sep 17 00:00:00 2001 From: Stephane Grosjean Date: Fri, 23 Jan 2015 11:31:23 +0100 Subject: [PATCH] can: peak_usb: export pcan_usb_pro functions Add support for the following new PEAK-System technik CANFD USB adapters: PCAN-USB FD single CANFD channel USB adapter PCAN-USB Pro FD dual CANFD channels USB adapter The communication protocol has been developed using some mechanisms that did exist in the PCAN-USB Pro, thus, this patch also changes some previously static functions and data into global ones.
