If so, I suggest using custom macros to add them instead of adding it at every use. Something like: #define rtl_err(dev, fmt, ...) \ dev_err(dev, "%s: " fmt, __func__, ##__VA_ARGS__) #define rtl_notice(dev, fmt, ...) \ dev_notice(dev, "%s: " fmt, __func__, ##__VA_ARGS__) #define rtl_warn(dev, fmt, ...) \ dev_warn(dev, "%s: " fmt, __func__, ##__VA_ARGS__) #define rtl_info(dev, fmt, ...) \ dev_info(dev, "%s: " fmt, __func__, ##__VA_ARGS__) > +static void rtl8xxxu_int_complete(struct urb *urb) > +{ > + struct rtl8xxxu_priv *priv = (struct rtl8xxxu_priv *)urb->context; > + struct device *dev = &priv->udev->dev; > + int i, ret; > + > + dev_dbg(dev, "%s: status %i\n", __func__, urb->status); > + if (urb->status == 0) { > + for (i = 0; i < USB_INTR_CONTENT_LENGTH; i++) { > + printk("%02x ", priv->int_buf[i]); > + if ((i & 0x0f) == 0x0f) > + printk("\n"); > + } print_hex_dump(); > +static int rtl8xxxu_probe(struct usb_interface *interface, > + const struct usb_device_id *id) > +{ [] > + dev_info(&udev->dev, "RTL8723au MAC %02x:%02x:%02x:%02x:%02x:%02x\n", > + priv->efuse_wifi.efuse.mac_addr[0], > + priv->efuse_wifi.efuse.mac_addr[1], > + priv->efuse_wifi.efuse.mac_addr[2], > + priv->efuse_wifi.efuse.mac_addr[3], > + priv->efuse_wifi.efuse.mac_addr[4], > + priv->efuse_wifi.efuse.mac_addr[5]); %pM [] > +struct rtl8xxxu_priv { [] > + u32 has_wifi:1; > + u32 has_bluetooth:1; > + u32 enable_bluetooth:1; > + u32 has_gps:1; > + u32 vendor_umc:1; > + u32 has_polarity_ctrl:1; > + u32 has_eeprom:1; > + u32 boot_eeprom:1; > + u32 ep_tx_high_queue:1; > + u32 ep_tx_normal_queue:1; > + u32 ep_tx_low_queue:1; > + u32 path_a_hi_power:1; These might be better as bool instead of packed bitfields. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
