From: Wei Yongjun <weiyongjun1@xxxxxxxxxx> [ Upstream commit 9b844b087124c1538d05f40fda8a4fec75af55be ] Call spi_master_get() holds the reference count to master device, thus we need an additional spi_master_put() call to reduce the reference count, otherwise we will leak a reference to master. This commit fix it by removing the unnecessary spi_master_get().
