Use template string as opposed to function name. Add a blank line after declaration to improve readability. Replace symbolic permissions with octal values. Use usleep_range for small msec values due to the fact that msleep() less than 20ms may have unexpected behavior/sleep longer. This patch removes all checkpatch warnings. - https://lkml.org/lkml/2016/8/2/1945 - Documentation/timers/timers-howto.rst Signed-off-by: Nigel Christian <nigel.l.christian@xxxxxxxxx> --- drivers/bluetooth/hci_qca.c | 11 ++++++----- 1 file changed, 6 insertions(+), 5 deletions(-) diff --git a/drivers/bluetooth/hci_qca.c b/drivers/bluetooth/hci_qca.c index 2d3f1f179a1e..22da59d8f471 100644 --- a/drivers/bluetooth/hci_qca.c +++ b/drivers/bluetooth/hci_qca.c @@ -555,7 +555,7 @@ static int qca_open(struct hci_uart *hu) struct qca_serdev *qcadev; struct qca_data *qca; - BT_DBG("hu %p qca_open", hu); + BT_DBG("hu %p %s", hu, __func__); if (!hci_uart_has_flow_control(hu)) return -EOPNOTSUPP; @@ -631,7 +631,7 @@ static void qca_debugfs_init(struct hci_dev *hdev) ibs_dir = debugfs_create_dir("ibs", hdev->debugfs); /* read only */ - mode = S_IRUGO; + mode = 0444; debugfs_create_u8("tx_ibs_state", mode, ibs_dir, &qca->tx_ibs_state); debugfs_create_u8("rx_ibs_state", mode, ibs_dir, &qca->rx_ibs_state); debugfs_create_u64("ibs_sent_sleeps", mode, ibs_dir, @@ -658,7 +658,7 @@ static void qca_debugfs_init(struct hci_dev *hdev) debugfs_create_u32("vote_off_ms", mode, ibs_dir, &qca->vote_off_ms); /* read/write */ - mode = S_IRUGO | S_IWUSR; + mode = 0644; debugfs_create_u32("wake_retrans", mode, ibs_dir, &qca->wake_retrans); debugfs_create_u32("tx_idle_delay", mode, ibs_dir, &qca->tx_idle_delay); @@ -1215,6 +1215,7 @@ static int qca_recv(struct hci_uart *hu, const void *data, int count) qca_recv_pkts, ARRAY_SIZE(qca_recv_pkts)); if (IS_ERR(qca->rx_skb)) { int err = PTR_ERR(qca->rx_skb); + bt_dev_err(hu->hdev, "Frame reassembly failed (%d)", err); qca->rx_skb = NULL; return err; @@ -1302,7 +1303,7 @@ static int qca_set_baudrate(struct hci_dev *hdev, uint8_t baudrate) /* Give the controller time to process the request */ if (qca_is_wcn399x(qca_soc_type(hu))) - msleep(10); + usleep_range(1000, 10000); else msleep(300); @@ -1350,7 +1351,7 @@ static int qca_send_power_pulse(struct hci_uart *hu, bool on) if (on) msleep(100); else - msleep(10); + usleep_range(1000, 10000); return 0; } -- 2.28.0
