commit 057b8945f78f76d0b04eeb5c27cd9225e5e7ad86 upstream.
In fsl_lpspi_probe an SPI controller is allocated either via spi_alloc_slave or spi_alloc_master. In all but one error cases this controller is put by going to error handling code. This commit fixes the case when pm_runtime_get_sync fails and it should go to the error handling path.
