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")
