Subject: gianfar: Fix use-after-of_node_put() in gfar_of_init().
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ee76db5e9e9896312f001790855a798472440328;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

gianfar: Fix use-after-of_node_put() in gfar_of_init().

We can't put 'mdio' until after we've used it in the
fsl_pq_mdio_bus_name() call.
