No, this is wrong. The message should say something like "UBI: block", or
otherwise the user will think this comes from the block subsystem.
Please use some pr_fmt for this. Something like this before the headers
should be enough:
#define pr_fmt(fmt) "UBI: block:" fmt
You can then use pr_{info,warn,err} without the prefix like this:
pr_info("whatever");
Which prints "UBI: block: whatever".
See arch/arm/kernel/perf_event.c for an example of how this works.
Also:

Please replace the level properly ubi_err -> pr_err, ubi_warn -> pr_warn, etc.
