From ff268b56ce8c86be920e1e6a15d68b168bed66c9 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Mon, 1 Jun 2015 18:47:54 -0700 Subject: [PATCH] regulator: core: Don't spew backtraces on duplicate sysfs We don't consider a failure to add the sysfs node as a problem, so use sysfs_create_link_nowarn() so that we don't print a backtrace when duplicated files exist. Also, downgrade the printk message to a debug statement so that we're quiet here. This allows multiple drivers to request a CPU's regulator so that CPUfreq and AVSish drivers can coexist.
