From: Wei Yongjun <weiyongjun1@xxxxxxxxxx> [ Upstream commit a23faea76d4cf5f75decb574491e66f9ecd707e7 ] 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().
