"_raw_spin_lock" undefined for Stretch on Pi 3 B+

[Mr Slugre]

I'm trying to compile a driver on the RaspberryPi 3 B+ (using Raspbian Stretch) and I get the following warnings:

WARNING: "_raw_spin_lock_bh" [/home/pi/linuxcan/linuxcan/common/kvcommon.ko] undefined!
WARNING: "_raw_spin_unlock_irqrestore" [/home/pi/linuxcan/linuxcan/common/kvcommon.ko] undefined!
WARNING: "_raw_spin_unlock_bh" [/home/pi/linuxcan/linuxcan/common/kvcommon.ko] undefined!
WARNING: "_raw_spin_lock" [/home/pi/linuxcan/linuxcan/common/kvcommon.ko] undefined!
WARNING: "_raw_spin_lock_irqsave" [/home/pi/linuxcan/linuxcan/common/kvcommon.ko] undefined!

These seems like serious warnings to me, and when trying to load the module, I get the following error:

Here I assume that the "disagrees about version of symbol" has something to do with the missing "_raw_spin_lock" above...

The code is using "raw_spinlock" calls which seems to be translated into these "_raw_spin_lock" by 'linux/spinlock.h' but from here I have no clue what to look for...

I have successfully built the same driver on a Raspberry Pi 3 Model B Rev 1.2 (i.e. not a '+') using identical FW version hash and version of Linux kernel

The driver I'm trying to compile is available at https://www.kvaser.com/downloads-kvaser/?utm_source=software&utm_ean=7330130980754&utm_status=latest

I just retested this on a new RPI3B+, and it works if you read and follow the blog https://www.kvaser.com/developer-blog/building-canlib-linuxcan-raspberry-pi/

When the build failed, I probably used the wrong symbols:

# For RaspberryPi Model B and B+
$ wget https://raw.github.com/raspberrypi/firmware/$RPI_FW_REV/extra/Module.symvers

# For RaspberryPi 2 and 3
$ wget https://raw.github.com/raspberrypi/firmware/$RPI_FW_REV/extra/Module7.symvers -O Module.symvers
