usb: gadget: f_fs: use complete() instead complete_all()
There is only one waiter for the completion, therefore there is no need to use complete_all(). Let's make that clear by using complete() instead of complete_all(). The usage pattern of the completion is: waiter context waker context reinit_completion() usb_esp_queue() wait_for_completion_interruptible() ffs_ep0_complete() complete() Acked-by: Michal Nazarewicz <mina86@mina86.com> Signed-off-by: Daniel Wagner <daniel.wagner@bmw-carit.de> Cc: Felipe Balbi <balbi@kernel.org> Cc: Michal Nazarewicz <mina86@mina86.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: linux-usb@vger.kernel.org Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
