regulator: fixed: Remove workaround to handle of_get_named_gpio() return
The GPIO interface of_get_named_gpio() has implemented the proper error returns even EPROBE_DEFER and hence caller need not to implement any workaround for translating the returned error. Remove the workaround implemented to handle the return of of_get_named_gpio(). Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@kernel.org>
