Subject: [PATCH 11/11] spi: Respect all error codes from dev_pm_domain_attach()
Date: Thu, 26 Apr 2018 10:53:10 +0200	[thread overview]
Message-ID: <1524732790-2234-12-git-send-email-ulf.hansson@linaro.org> (raw)
In-Reply-To: <1524732790-2234-1-git-send-email-ulf.hansson@linaro.org>

The limitation of being able to check only for -EPROBE_DEFER from
dev_pm_domain_attach() has been removed. Hence let's respect all error
codes and bail out accordingly.
