I have opted for the mutex instead. I have just sent an updated version fixing another issue in my code: The mutex can't be included in pi433_instance because we have to lock it before dereferencing our pi433_instance pointer. The best solution I could think of was to create a wrapper struct pi433_data which would contain pointers to the pi433_instance and its mutex. I couldn't find any similar situation in the kernel, so I'm not sure it's the right way to go though. Thanks !
