Subject: [PATCH] rtl8188eu: core: Remove NULL test before vfree
Date: Mon, 16 Jan 2017 09:48:19 +0530 [thread overview]
Message-ID: <1484540299-31056-1-git-send-email-mayhs11saini@gmail.com> (raw)
vfree frees the virtually continuous block of memory beginning at
addr. If addr is NULL, no operation is performed. So, NULL test is not
needed before vfree().
