Subject: [PATCH 2/2] spi: spi_tegra: calling spi_unregister_master instead of spi_master_put in spi_tegra_remove
Date: Wed, 11 May 2011 21:28:16 +0800 [thread overview]
Message-ID: <1305120496.6324.8.camel@phoenix> (raw)
In-Reply-To: <1305120420.6324.6.camel@phoenix>
spi_master_put() should only be used in error handling.
Once spi_register_master() returns success, we should call
spi_unregister_master() instead.
