From: Nishad Kamdar
Date: Wed Aug 22 2018 - 04:33:12 EST

This patchset fixes the four debug macros N_MSG, ERR_MSG, INIT_MSG and
IRQ_MSG. Each patch fixes one particular macro and its usages.

For N_MSG, replaces printk with dev_<level> without __func__ or __LINE__
or current->comm and current->pid. Removes the do {} while(0) loop for
the single statement macro.

For ERR_MSG and IRQ_MSG, makes the same changes as those for N_MSG, but
further drops the macros and replaces their usages with dev_<level>.

Removes the INIT_MSG macro and its usages.

Changes in v4:
- Create multiple patches, one for each type of macro being

Changes in v3:
- Replace usages of ERR_MSG and IRQ_MSG with dev_err() in code itself.
- Remove all INIT_MSG usages.
- Drop ERR_MSG, INIT_MSG and IRQ_MSG from dbg.h.

Changes in v2:
- Replace printk with dev_<level>.
- Remove __func__, __LINE__, current->comm, current->pid from arguments.
- Remove the do {} while(0) loop from these macros.
- Modify commit message to include other changes.
