Commit Message

Umang Jain Sept. 13, 2023, 6:55 p.m. UTC 
  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.
