[PATCH v1 3/4] staging: vc04: Convert(and rename) vchiq_log_info() to use dynamic debug

Umang Jain
2023-10-19T08:22:20Z

Convert(and rename) vchiq_log_info() custom logging wrapping based on
printk to use dynamic debug. The wrapper is now renamed to
vchiq_log_debug() since most of the usage is around printing debug
information. The log category is dictated by enum vchiq_log_category
which will become the part of the debug string format that will be
logged to dynamic debug (for grep).

All the vchiq_log_info() calls are adjusted to use the
modified wrapper vchiq_log_debug().

The existing custom logging for vchiq_log_info() also tries
to log trace messages using SRVTRACE_LEVEL. This is simply
moved to use the vchiq_log_debug() directly.
