[PATCH v4 2/4] staging: mt7621-mmc: Fix debug macro ERR_MSG and its usages

From: Nishad Kamdar
Date: Wed Aug 22 2018 - 04:43:19 EST


Replace all usages of ERR_MSG with with dev_<level> without __func__
or __LINE__ or current->comm and current->pid. Remove the do {}
while(0) loop for the single statement macro. Drop ERR_MSG from dbg.h.
Issue found by checkpatch.
