From: Wei Yongjun Date: Sat, 20 Aug 2016 15:25:32 +0000 (+0000) Subject: spi: spi-fsl-dspi: Drop extra spi_master_put in device remove function X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6999aeabbb703a81a204cb6f9f8f151759a99ac4;p=linux-beck.git spi: spi-fsl-dspi: Drop extra spi_master_put in device remove function The call sequence spi_alloc_master/spi_register_master/spi_unregister_master is complete; it reduces the device reference count to zero, which and results in device memory being freed. The subsequent call to spi_master_put is unnecessary and results in an access to free memory. Drop it.
