First patch removes a restriction that prevents null_blk to load with (nr_devices == 0). This restriction breaks applications, so it's a bug. I have tested it running the kernel with `null_blk.nr_devices=0`. In the previous series I have changed the type of var nr_devices, but I forgot to change the type at module_param(). The second patch fix that. The third patch uses a cleaver approach to make log messages consistent using pr_fmt and the last one add a note on how to do that at the coding style documentation.
