    Subject[PATCH 5.10 083/306] pinctrl: single: Fix error return code in pcs_parse_bits_in_pinctrl_entry()
    Date
    From: Zhen Lei <thunder.leizhen@huawei.com>

    [ Upstream commit d789a490d32fdf0465275e3607f8a3bc87d3f3ba ]

    Fix to return -ENOTSUPP instead of 0 when PCS_HAS_PINCONF is true, which
    is the same as that returned in pcs_parse_pinconf().

    Fixes: 4e7e8017a80e ("pinctrl: pinctrl-single: enhance to configure multiple pins of different modules")
