Subject[PATCH v2 3/4] null_blk: format pr_* logs with pr_fmt
Date
Instead of writing "null_blk: " at the beginning of each
pr_err/info/warn log message, format messages using pr_fmt() macro.

Signed-off-by: André Almeida <andrealmeid@collabora.com>
---
Changes from v1:
- Use #undef instead of reorder #includes
- Use KBUILD_MODNAME instead of using the hardcoded module name
