From bc554d1e94bdfdcca540c1a8b2c01a930a437a15 Mon Sep 17 00:00:00 2001 From: Nishad Kamdar Date: Sat, 1 Sep 2018 03:49:43 +0530 Subject: [PATCH] staging: mt7621-mmc: Fix debug macro ERR_MSG and its usages Replace all usages of ERR_MSG with with dev_ 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.
