[PATCH] spi: lpspi: fix memory leak in fsl_lpspi_probe

[Navid Emamdoost]

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.

Fixes: 944c01a889d9 ("spi: lpspi: enable runtime pm for lpspi")
