changes for raspian 4.19.42+

[jkarstest]

Hi.
In the attached rfm12b.c file I did changes in the 2 timer_callbacks to compile with new kernel.
might you will update the code ? the module runs on a pi-ZERO , I testet only receiving without ACK but that works for me :)
Thank you again for that stable little module.
Parts of your documentation seem to be deprecated, I just installed the kernel-source via apt-get as far as I remember...

Hi Jens, thanks for your work on this module regarding the newer Raspis. And of course thanks to @gkaindl for the work, too. Your changes are very appreciated, I can compile them, load the module at bootup, but when accessing the RFB12B it fails to register the interrupt. I'm pulling my hair for a few hours already, but don't know how to fix this. You wrote, on Rpi Zero it works - any idea why it doesn't on a Rpi 3?
