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

Replace all usages of IRQ_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 IRQ_MSG from dbg.h.
Issue found by checkpatch.
