Subject: [PATCH 1/6] regulator: core: Don't spew backtraces on duplicate sysfs
Date: Mon, 1 Jun 2015 18:47:54 -0700 [thread overview]
Message-ID: <1433209679-31389-2-git-send-email-sboyd@codeaurora.org> (raw)
In-Reply-To: <1433209679-31389-1-git-send-email-sboyd@codeaurora.org>
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.
