From 95bbbe9a6663635b6cdef20c01c0ea32ec6987e4 Mon Sep 17 00:00:00 2001 From: Gabriele Mazzotta Date: Thu, 8 Jan 2015 19:41:34 +0100 Subject: [PATCH] ahci: Use dev_info() to inform about the lack of Device Sleep support According to the Serial ATA AHCI specification, Device Sleep is an optional feature and as such no errors should be printed if it's missing. Keep informing users, but use dev_info() instead of dev_err().
