[PATCH v2 19/25] usb: gadget: f_tcm: Decrement command ref count on cleanup

From: Thinh Nguyen
Date: Mon Jul 18 2022 - 22:12:46 EST


We submitted the command with TARGET_SCF_ACK_KREF, which requires
acknowledgment of command completion. If the command fails, make sure to
decrement the ref count.

Fixes: cff834c16d23 ("usb-gadget/tcm: Convert to TARGET_SCF_ACK_KREF I/O krefs")
