  1. Update linux_userspace.c 

    How did you make this work?
Like this, ioctl is never started and device address is nowhere used. Besides that, setting dev_addr was done after ioctl call,
Consequently, it failed.
With the proposed changed it runs on my Raspberry Pi Zero. 

Nevertheless the proposed force mode code only returns static values. 
Could be fixed by using the normal mode with code as proposed in the project's documentation.

Error handling for user read would be fine, but ok, it's up to each user.
Still I have some doubts when I compare this to I2C read&write methods of WiringPi, which calls ioctl before each access.
Did not follow up here, but guess it's needed when you want to access different devices within a program.
