The commit message is missing description of why
some printk(KERN_INFO are converted to dev_dbg

Also, it'd be better to remove the dbgcm macro
altogether and just use dev_dbg.

The dbgcm variable and macro isn't really necessary
because dynamic_debug has all the same capability.

This likely should not be dev_dbg.
