Subject: [PATCH] pinctrl: mediatek: add a check for error in
mtk_pinconf_bias_get_rsel()
All the other mtk_hw_get_value() calls have a check for "if (err)" so
we can add one here as well. This silences a Smatch warning:
drivers/pinctrl/mediatek/pinctrl-mtk-common-v2.c:819 mtk_pinconf_bias_get_rsel()
error: uninitialized symbol 'pd'.
Fixes: fb34a9ae383a ("pinctrl: mediatek: support rsel feature")
