X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b3300146aa8efc5d3937fd33f3cfdc580a3843bc;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git phy:icplus:fix Auto Power Saving in ip101a_config_init. This patch fixes Auto Power Saving configuration in ip101a_config_init which was broken as there is no phy register write followed after setting IP101A_APS_ON flag. This patch also fixes the return value of ip101a_config_init. Without this patch ip101a_config_init returns 2 which is not an error accroding to IS_ERR and the mac driver will continue accessing 2 as valid pointer to phy_dev resulting in memory fault.
