From 759c409bc5fc496cbc22cd0b392d3cbb0c0e23eb Mon Sep 17 00:00:00 2001 From: Dinghao Liu Date: Mon, 25 Sep 2023 10:41:33 +0800 Subject: [PATCH] mfd: dln2: Fix double put in dln2_probe The dln2_free() already contains usb_put_dev(). Therefore, the redundant usb_put_dev() before dln2_free() may lead to a double free.
