[PATCH 4/7] spi: mt65xx: Move pm_runtime_enable() call to remove all gotos

From: AngeloGioacchino Del Regno
Date: Wed Apr 06 2022 - 09:19:54 EST


The last goto in the probe function can be removed by calling
pm_runtime_enable() right before devm_spi_register_master(), as
only some init checks were being performed after enabling pm.
This is a cleanup and brings no functional changes.
