Subject[PATCH 24/24] Staging: comedi: fix code cleanup in daqboard2000.c
Date
This is a patch to the daqboard2000.c file that fixes up a
warning found by the checkpatch.pl tool.
Converted function name to "%s", __func__.
Converted printks to dev_printk.
Fixed brace coding style issue.
Removed unnecessary printk statements.
