I think that here, you should do return val & MTK_BT_RST_DONE; and then, for the readx_poll_timeout, you simply check if this function returned 1, like: err = readx_poll_timeout(btusb_mtk_reset_done, hdev, val, val, 20000, 1000000); > +} > + > static int btusb_mtk_setup(struct hci_dev *hdev) > { > struct btusb_data *data = hci_get_drvdata(hdev); > @@ -2922,7 +2930,7 @@ static void btusb_mtk_cmd_timeout(struct hci_dev *hdev) > { > struct btusb_data *data = hci_get_drvdata(hdev); > u32 val; > - int err, retry = 0; > + int err; > > /* It's MediaTek specific bluetooth reset mechanism via USB */ > if (test_and_set_bit(BTUSB_HW_RESET_ACTIVE, &data->flags)) { > @@ -2953,18 +2961,14 @@ static void btusb_mtk_cmd_timeout(struct hci_dev *hdev) > btusb_mtk_uhw_reg_write(data, MTK_BT_SUBSYS_RST, 0); > btusb_mtk_uhw_reg_read(data, MTK_BT_SUBSYS_RST, &val); > > - /* Poll the register until reset is completed */ > - do { > - btusb_mtk_uhw_reg_read(data, MTK_BT_MISC, &val); > - if (val & MTK_BT_RST_DONE) { > - bt_dev_dbg(hdev, "Bluetooth Reset Successfully"); > - break; > - } > + err = readx_poll_timeout(btusb_mtk_reset_done, hdev, val, > + val & MTK_BT_RST_DONE, > + 20000, 1000000); > + if (err < 0) > + bt_dev_err(hdev, "Reset timeout"); > > - bt_dev_dbg(hdev, "Polling Bluetooth Reset CR"); > - retry++; > - msleep(MTK_BT_RESET_WAIT_MS); > - } while (retry < MTK_BT_RESET_NUM_TRIES); > + if (val & MTK_BT_RST_DONE) You're already checking `if (err < 0)`, so this check is redundant. If the polling didn't return a timeout, the register value contains MTK_BT_RST_DONE for sure, so you can safely remove this check. > + bt_dev_dbg(hdev, "Bluetooth Reset Successfully"); > Regards, Angelo
