[PATCH 9/9] staging: vc04_services: Drop vchiq_log_debug() in favour of dev_dbg

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Drop vchiq_log_debug() macro which wraps dev_dbg(). Introduce the usage
of dev_dbg() directly.

Remove the entry from TODO regarding custom logging. VC04 is now
aligned according to the standard kernel logging mechanisms.
