[PATCH v2 0/5] staging: vc04_services: Drop custom logging

[Umang Jain]

This series also removes the vchiq_log_* macro and makes use of dev_dbg()
directly.

Patch 1/5 is fix. It prevents passing NULL to one of vchiq_log_error().
The function there in question, does not have any users as of
now. However, it is going to be used by the vc-sm-cma and bcm2835-isp
drivers (posted on list for review [1]). There was discussion on v1,
whether I should drop and add the function later, however, didn't 
conclude.

Patch 2/5 removes vchiq_log_error() macro
Patch 3/5 removes vchiq_log_warning() macro
Patch 4/5 removes vchiq_log_trace() macro
Patch 5/5 removes vchiq_log_debug() macro

This completes the following TODO item:

```
* Cleanup logging mechanism

The driver should probably be using the standard kernel logging mechanisms
such as dev_info, dev_dbg, and friends.
```

Changes in v2:
- Separate out one fixup patch from v1 (Patch 1/9)and send separately
- Drop usage of log_type() and log_category() helpers. Directly use
  dev_dbg() as suggested by Greg KH.
- Drop __func__ annotation from all logs. Dynamic debug has 'f'
  decorator flag which can be used instead of manual __func__
- Reword commit messages.
