[ Upstream commit236152dd9b] In the pin_config_set function, when handling PIN_CONFIG_BIAS_PULL_DOWN or PIN_CONFIG_BIAS_PULL_UP, the function calls pcs_pinconf_clear_bias() which writes the register. However, the subsequent operations continue using the stale 'data' value from before the register write, effectively causing the bias clear operation to be overwritten and not take effect. Fix this by reading the 'data' value from the register after calling pcs_pinconf_clear_bias(). This bug seems to have existed when this code was first merged in commit9dddb4df90("pinctrl: single: support generic pinconf").
