      USB: Remove pointless conditional in drivers/usb/serial/io_ti.c::edge_shutdown() · 0d46c007
      由 Jesper Juhl 提交于 
      Coverity scan found (CID: 1708) this in
drivers/usb/serial/io_ti.c::edge_shutdown() :

...
2797 		for (i=0; i < serial->num_ports; ++i) {
2798 			edge_port = usb_get_serial_port_data(serial->port[i]);
2799 			edge_remove_sysfs_attrs(edge_port->port);
2800 			if (edge_port) {
2801 				edge_buf_free(edge_port->ep_out_buf);
2802 				kfree(edge_port);
2803 			}
2804 			usb_set_serial_port_data(serial->port[i], NULL);
2805 		}
...

It's complaining that we dereference 'edge_port' in line 2799 which
makes the test of that pointer against NULL in 2800 pointless, since if
edge_port was actually NULL we'd have crashed already before reaching
line 2800.
Reading the edge_open() function it seems to me that the pointer
returned by usb_get_serial_port_data(serial->port[i]) and stored in
'edge_port' can never actually be NULL here, so the test is entirely
superfluous (even if it could be NULL it would be pointless here,
ignoring the then possible crash in that case, since both
edge_buf_free() and kfree() can handle being passed NULL pointers.

This patch removes the pointless conditional (and also makes a few
tiny style corrections now that I was in the area anyway).

      USB: mos7720, mos7840: remove redundant urb check · e94fa28f
      由 Florin Malita 提交于 
      Coverity (1709, 1710, 1711, 1712, 1713) actually flagged these as
REVERSE_INULLs (NULL check performed after dereference). But looking at
the other drivers I can't see any similar tests and the USB core already
makes sure urb is non-null - so might as well get rid of the checks.
