Locking at the resulting tpa6130a2.c I suggest to add a patch
removing the useless "goto err_gpio" in tpa6130a2_probe().

Also switching to gpiod_get() safes some more lines of code.
It may make sense to postpone this to 4.9, though (this change
involves removing the gpio from the platform data and the rx51
will become DT only in 4.8).
