Subject: [PATCH -mm] drivers/usb/serial/bus.c: Fix incompatible pointer type warning
Date: Sunday, September 2, 2007 - 4:12 pm

drivers/usb/serial/bus.c: In function $B!F(Jusb_serial_bus_deregister$B!G(J:
drivers/usb/serial/bus.c:185:
warning: passing argument 1 of $B!F(Jfree_dynids$B!G(J from incompatible pointer type

Above build warning comes when CONFIG_HOTPLUG=n because argument of
free_dynids() in serial/bus.c is a struct usb_serial_driver, not a
struct usb_driver. This is not a runtime bug, because the function
is an empty stub and never dereferences the passed pointer anyway.
