Subject: [PATCH v6 2/3] staging: mt7621-mmc: Fix debug macro ERR_MSG and its
usages
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. Delete commented
ERR_MSG() usage. Drop ERR_MSG from dbg.h. Issue found by checkpatch.
Signed-off-by: Nishad Kamdar <nishadkamdar@...il.com>

Changes in v6:
- No change
Changes in v5:
- Remove commented ERR_MSG() usage.
