commit c4e00daa changed __dev_printk in a way that broke dynamic-debug's ability to control the dynamic prefix of dev_dbg(dev,..), but not dev_dbg(NULL,..) or pr_debug(..), which is why it wasnt noticed sooner. When dev==NULL, __dev_printk() just calls printk(), which just works. But otherwise, it assumed that level was always a string like "<L>" and just plucked out the 'L', ignoring the rest. However, dynamic_emit_prefix() adds "[tid] module:func:line:" to the string, those additions all got lost. Signed-off-by:
