Subject: [PATCH v3 -next] mtd: docg3: Fix a possible memory leak of mtd->name
Date: Wed, 23 Jan 2019 17:28:19 +0800 [thread overview]
Message-ID: <20190123092819.5020-1-yuehaibing@huawei.com> (raw)
In case DOC_CHIPID_G3, mtd->name is not freed in err handling path,
which is alloced by kasprintf(). Fix this by using devm_kasprintf().
