From 7c43161c11d7f40e38db9a1adb61347f06127796 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Fri, 27 Jan 2012 17:23:58 +0000 Subject: sfc: Warn if unable to create MTDs Log an explicit warning if we are unable to create MTDs for a net device. Also correct the comment about why mtd_device_register() may fail; there is no longer an MTD table to fill up.
