soc: imx: gpc: fix domain_index sanity check issue
ARRAY_SIZE(imx_gpc_domains) represents all power domains supported by different SoCs. Driver should use SoC specific of_id_data->num_domains instead to do power domain index sanity check. e.g. MX6Q supports two power domains while MX6SL supports three. Fixes: 721cabf6c660 ("soc: imx: move PGC handling to a new GPC driver") Acked-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Dong Aisheng <aisheng.dong@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
