From 0730d52a86919300a39a2be37f6c140997dfb82f Mon Sep 17 00:00:00 2001 From: Dmitry Kasatkin Date: Tue, 27 Aug 2013 17:47:35 +0300 Subject: [PATCH] xhci:prevent "callbacks suppressed" when debug is not enabled When debug is not enabled and dev_dbg() will expand to nothing, log might be flooded with "callbacks suppressed". If it was not done on purpose, better to use dev_dbg_ratelimited() instead.
