From b16d7577db8800a798fe4dae7d85fd985507c978 Mon Sep 17 00:00:00 2001 From: Qiang Ning Date: Thu, 30 Mar 2023 10:43:53 +0800 Subject: [PATCH] mfd: dln2: Fix memory leak in dln2_probe() [ Upstream commit 96da8f148396329ba769246cb8ceaa35f1ddfc48 ] When dln2_setup_rx_urbs() in dln2_probe() fails, error out_free forgets to call usb_put_dev() to decrease the refcount of dln2->usb_dev. Fix this by adding usb_put_dev() in the error handling code of dln2_probe().
