Subject: [RFC PATCH v2 2/4] staging: vc04: Convert vchiq_log_warning() to use dynamic debug
As part of ongoing series i.e. moving away from printk
based logging to dynamic debug logging mechanism, this patch
converts vchiq_log_warning() wrapper to use dynamic debug.
The log category is dictated by enum vchiq_log_category
which will become the part of the warning string format that
will be logged to dynamic debug (for grep).
All the vchiq_log_warning() calls are adjusted to use the
modified wrapper.
