HID: Fix uninitialized variable "size" in hid-wiimote-debug
This variable is initialized conditionally, based on whether a wiimote call succeeds. However, the logic is not obvious to the compiler so it throws a warning. Eliminate the warning by initializing "size" to 0. The warning is: files/drivers/hid/hid-wiimote-debug.c:69:18: warning: 'size' may be used uninitialized in this function [-Wmaybe-uninitialized] Signed-off-by: Simon Que <sque@chromium.org> Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
