    Subject[PATCH 5.18 037/339] iio: adc: sc27xx: Fine tune the scale calibration values
    Date
    From: Cixi Geng <cixi.geng1@unisoc.com>

    [ Upstream commit 5a7a184b11c6910f47600ff5cbbee34168f701a8 ]

    Small adjustment the scale calibration value for the sc2731,
    use new name sc2731_[big|small]_scale_graph_calib, and remove
    the origin [big|small]_scale_graph_calib struct for unused.
