From: Jesper Juhl <jj@xxxxxxxxxxxxx> In drivers/usb/renesas_usbhs/mod_gadget.c::usbhsg_recip_run_handle() the Coverity Prevent checker currently flags a warning about possibly uninitialized use of 'ret' i usbhsg_recip_run_handle(). It does this since it assumes we take one of the non-default branches in the switch and then subsequently take the false branch in the 'if (func)' case below. This exact scenario will never happen, but Coverity can't see that for some reason. This patch initializes 'ret' to '0' when it is declared which should shut up this report and won't really hurt - so why not? At least then it's clear that 'ret' is always initialized..
