While this patch fixes the warnings as well, I suggest to replace the dev_dbg/dev_err traces in these functions to use the dev variable instead of info->dev, to be consistent with the usage in the rest of the file. regards Suman > > Reported-by: Hulk Robot <hulkci@huawei.com> > Signed-off-by: YueHaibing <yuehaibing@huawei.com> > --- > drivers/firmware/ti_sci.c | 8 -------- > 1 file changed, 8 deletions(-) > > diff --git a/drivers/firmware/ti_sci.c b/drivers/firmware/ti_sci.c > index 86b2727..8c1a961 100644 > --- a/drivers/firmware/ti_sci.c > +++ b/drivers/firmware/ti_sci.c > @@ -2032,14 +2032,12 @@ static int ti_sci_cmd_ring_config(const struct ti_sci_handle *handle, > struct ti_sci_msg_hdr *resp; > struct ti_sci_xfer *xfer; > struct ti_sci_info *info; > - struct device *dev; > int ret = 0; > > if (IS_ERR_OR_NULL(handle)) > return -EINVAL; > > info = handle_to_ti_sci_info(handle); > - dev = info->dev; > > xfer = ti_sci_get_one_xfer(info, TI_SCI_MSG_RM_RING_CFG, > TI_SCI_FLAG_REQ_ACK_ON_PROCESSED, > @@ -2101,14 +2099,12 @@ static int ti_sci_cmd_ring_get_config(const struct ti_sci_handle *handle, > struct ti_sci_msg_rm_ring_get_cfg_req *req; > struct ti_sci_xfer *xfer; > struct ti_sci_info *info; > - struct device *dev; > int ret = 0; > > if (IS_ERR_OR_NULL(handle)) > return -EINVAL; > > info = handle_to_ti_sci_info(handle); > - dev = info->dev; > > xfer = ti_sci_get_one_xfer(info, TI_SCI_MSG_RM_RING_GET_CFG, > TI_SCI_FLAG_REQ_ACK_ON_PROCESSED, > @@ -2284,14 +2280,12 @@ static int ti_sci_cmd_rm_udmap_tx_ch_cfg(const struct ti_sci_handle *handle, > struct ti_sci_msg_hdr *resp; > struct ti_sci_xfer *xfer; > struct ti_sci_info *info; > - struct device *dev; > int ret = 0; > > if (IS_ERR_OR_NULL(handle)) > return -EINVAL; > > info = handle_to_ti_sci_info(handle); > - dev = info->dev; > > xfer = ti_sci_get_one_xfer(info, TISCI_MSG_RM_UDMAP_TX_CH_CFG, > TI_SCI_FLAG_REQ_ACK_ON_PROCESSED, > @@ -2354,14 +2348,12 @@ static int ti_sci_cmd_rm_udmap_rx_ch_cfg(const struct ti_sci_handle *handle, > struct ti_sci_msg_hdr *resp; > struct ti_sci_xfer *xfer; > struct ti_sci_info *info; > - struct device *dev; > int ret = 0; > > if (IS_ERR_OR_NULL(handle)) > return -EINVAL; > > info = handle_to_ti_sci_info(handle); > - dev = info->dev; > > xfer = ti_sci_get_one_xfer(info, TISCI_MSG_RM_UDMAP_RX_CH_CFG, > TI_SCI_FLAG_REQ_ACK_ON_PROCESSED, >
