From 262ad4f3d1f9e008c9ba38f4f3424ea71b79d6a0 Mon Sep 17 00:00:00 2001 From: Yang Yingliang Date: Thu, 10 Nov 2022 08:24:23 +0000 Subject: [PATCH] media: solo6x10: fix possible memory leak in solo_sysfs_init() If device_register() returns error in solo_sysfs_init(), the name allocated by dev_set_name() need be freed. As comment of device_register() says, it should use put_device() to give up the reference in the error path. So fix this by calling put_device(), then the name can be freed in kobject_cleanup().
