When receiving a nec repeat, ensure the correct scancode is repeated rather than a random value from the stack. This removes the need for the bogus uninitialized_var() and also fixes the warnings: drivers/media/usb/dvb-usb/dib0700_core.c: In function ‘dib0700_rc_urb_completion’: drivers/media/usb/dvb-usb/dib0700_core.c:679: warning: ‘protocol’ may be used uninitialized in this function [sean addon: So after writing the patch and submitting it, I've bought the hardware on ebay. Without this patch you get random scancodes on nec repeats, which the patch indeed fixes.] Signed-off-by: Sean Young Tested-by: Sean Young Signed-off-by: Arnd Bergmann Signed-off-by: Linus Torvalds Signed-off-by: Greg Kroah-Hartman --- drivers/media/usb/dvb-usb/dib0700_core.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) --- a/drivers/media/usb/dvb-usb/dib0700_core.c +++ b/drivers/media/usb/dvb-usb/dib0700_core.c @@ -677,7 +677,7 @@ static void dib0700_rc_urb_completion(st struct dvb_usb_device *d = purb->context; struct dib0700_rc_response *poll_reply; enum rc_type protocol; - u32 uninitialized_var(keycode); + u32 keycode; u8 toggle; deb_info("%s()\n", __func__); @@ -719,7 +719,8 @@ static void dib0700_rc_urb_completion(st poll_reply->nec.data == 0x00 && poll_reply->nec.not_data == 0xff) { poll_reply->data_state = 2; - break; + rc_repeat(d->rc_dev); + goto resubmit; } if ((poll_reply->nec.data ^ poll_reply->nec.not_data) != 0xff) { Patches currently in stable-queue which might be from sean@mess.org are queue-4.4/dib0700-fix-nec-repeat-handling.patch
