From e93b07244d6e1d6105df78b6117b00c940006b45 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Sat, 31 Aug 2013 20:25:52 +0800 Subject: [PATCH] spi: core: Fix spi_register_master error handling In the case spi_master_initialize_queue() fails, current code calls device_unregister() before return error from spi_register_master(). However, all the drivers call spi_master_put() in the error path if spi_register_master() fails. Thus we should call device_del() rather than device_unregister() before return error from spi_register_master(). This also makes all the spi_register_master() error handling consistent, because all other error paths of spi_register_master() expect drivers to call spi_master_put() if spi_register_master() fails.
