Subject[PATCH v3] mtd: nxp-spifi: release flash_np in nxp_spifi_probe()
Date
nxp_spifi_probe() increments refcnt of SPI flash device node by
of_get_next_available_child() and leaves it undecremented on both
successful and error paths.

Found by Linux Driver Verification project (linuxtesting.org).

Signed-off-by: Alexey Khoroshilov <khoroshilov@ispras.ru>

v3: Move of_node_put() before return value check as Boris Brezillon suggested.
