[PATCH v2 5/5] staging: vc04_services: Drop vchiq_log_debug() in favour of dev_dbg
Umang Jain
umang.jain at ideasonboard.com
Tue Nov 28 12:19:26 PST 2023
Drop vchiq_log_debug() macro which wraps dev_dbg(). Introduce the usage
of dev_dbg() directly.
Meanwhile at it, drop the usage of __func__ from the logs.
Dynamic debug supports this via the 'f' decorator flag.
Remove the entry from TODO regarding custom logging. VC04 is now
aligned according to the standard kernel logging mechanisms.
