Hello Dulshani Gunawardhana,
The patch 44ee8e801137: "staging: media: Use dev_err() instead of
pr_err()" from Oct 20, 2013, leads to the following
GCC warning:
drivers/staging/media/go7007/go7007-usb.c: In function ‘go7007_usb_probe’:
drivers/staging/media/go7007/go7007-usb.c:1100:13: warning: ‘go’ may be used uninitialized in this function [-Wuninitialized]
drivers/staging/media/go7007/go7007-usb.c
1049 static int go7007_usb_probe(struct usb_interface *intf,
1050 const struct usb_device_id *id)
1051 {
1052 struct go7007 *go;
1053 struct go7007_usb *usb;
1054 const struct go7007_usb_board *board;
1055 struct usb_device *usbdev = interface_to_usbdev(intf);
1056 unsigned num_i2c_devs;
1057 char *name;
1058 int video_pipe, i, v_urb_len;
1059
1060 dev_dbg(go->dev, "probing new GO7007 USB board\n");
^^^^^^^
1061
1062 switch (id->driver_info) {
1063 case GO7007_BOARDID_MATRIX_II:
1064 name = "WIS Matrix II or compatible";
1065 board = &board_matrix_ii;
1066 break;
There are several other uses of "go" before it has been initialized.
Probably you will just want to change these back to pr_info(). Some of
the messages are not very useful like:
dev_info(go->dev, "Sensoray 2250 found\n");
You can delete that one.
regards,
dan carpenter
