[PATCH v4] mtd: ubi: Extend UBI layer debug/messaging capabilities

Tanya Brokhman
2014-10-14T14:14:44Z

If there is more then one UBI device mounted, there is no way to
distinguish between messages from different UBI devices.
Add device number to all ubi layer message types.

The R/O block driver messages were replaced by pr_* since
ubi_device structure is not used by it.

Signed-off-by: Tanya Brokhman <tlinder@codeaurora.org>
---
Changes from V1:
- Compilation error fixed
- macros were updated to receive the ubi structure as
parameter and not just ubi_number
- Places in code, where ubi-messaging macros were used, but
ubi struct is not present yet (init phase), were updated
to just use pr_err or similar
Changes from V2:
- multi line messages layout, as requested by Artem
note that due to these changes checkpatch fails
Changes from V3:
- Compilation fix of block.c
- All ubi_* messages in block.c were replaced with pr_*

Note for reviewers:
The updated macros are all in ubi.h. All other file changes are just
technical changes for compilation (usage of the defined macros)
