Subject: [PATCH 3/4] spi: qup: Fix order of spi_register_master
Date: Tue, 13 May 2014 16:34:43 -0500	[thread overview]
Message-ID: <1400016884-9568-4-git-send-email-agross@codeaurora.org> (raw)
In-Reply-To: <1400016884-9568-1-git-send-email-agross@codeaurora.org>

This patch moves the devm_spi_register_master below the initialization of the
runtime_pm.  If done in the wrong order, the spi_register_master fails if any
probed slave devices issue SPI transactions.
