Subject: [RESEND PATCH] PM / devfreq: Propagate error from devfreq_add_device()
Date: Sun, 5 Nov 2017 21:27:41 -0800 [thread overview]
Message-ID: <20171106052741.445-1-bjorn.andersson@linaro.org> (raw)
Propagate the error of devfreq_add_device() in devm_devfreq_add_device()
rather than statically returning ENOMEM. This makes it slightly faster
to pinpoint the cause of a returned error.
Fixes: 8cd84092d35e ("PM / devfreq: Add resource-managed function for devfreq device")
Cc: stable@vger.kernel.org
Acked-by: Chanwoo Choi <cw00.choi@samsung.com>
