[ldv-project] [PATCH] spi: pic32: remove unnecessary of_node_get()

[Alexey Khoroshilov]

Almost all spi drivers assign spi master->dev.of_node from
its parent platform device without additional refcounting.
It seems of_node_get() in pic32_spi_probe() is unnecessary
and there is no corresponding of_node_put().
