Subject: pinctrl: spacemit: delete spacemit_pctrl_check_power()
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=97a061a300da59b2073006803113d258a40a9086;p=thirdparty%2Fkernel%2Flinux.git

pinctrl: spacemit: delete spacemit_pctrl_check_power()

As far as I can tell spacemit_pctrl_check_power(), called during the
custom implementation of dt_node_to_map, is redundant because
the driver's implementation generate_config performs the check too.
Removing this would allow the driver to use the newly added common
function pinctrl_generic_pinmux_dt_node_to_map().
