Subject: [PATCH 1/2] spi: spi_sh: calling spi_unregister_master instead of spi_master_put in spi_sh_remove
Date: Wed, 11 May 2011 21:27:00 +0800	[thread overview]
Message-ID: <1305120420.6324.6.camel@phoenix> (raw)

spi_master_put() should only be used in error handling.
Once spi_register_master() returns success, we should call
spi_unregister_master() instead.
