Subject: [Patch v2] staging: greybus: Replace gcam macros with direct dev log
 calls
Message-ID: <ZhRzWNiak1qOdJLL@jc-ubuntu-dev-korn-1>
Precedence: bulk
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline

Reported by checkpatch:

CHECK: Macro argument 'gcam' may be better as '(gcam)' to avoid
precedence issues

Inline standard calls to 'dev_*' kernel logging functions, in favor
of 'gcam_*' macros, to clear up gcam-related logging.

Signed-off-by: Jackson Chui <jacksonchui.qwerty@gmail.com>

---
Changes in v2:
  - Inline 'dev_*' logging functions, over wrappers and macros
    to just use the standard call.
  - Remove 'gcam_*' macros, since they are no longer used.
