X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a15a5eabae418ff91ebce8de3f6815433b49ad1d;p=linux.git

Bluetooth: btusb: Return error code when getting patch status failed

commit 995d948cf2e45834275f07afc1c9881a9902e73c upstream.

If there are failure cases in getting patch status, it should return the
error code (-EIO).

Fixes: fc342c4dc4087 ("Bluetooth: btusb: Add protocol support for MediaTek MT7921U USB devices")
