Subject: [PATCH 6/6] usb: raw-gadget: use kzalloc
Date: Sat, 12 Mar 2022 11:27:05 +0100 [thread overview]
Message-ID: <20220312102705.71413-7-Julia.Lawall@inria.fr> (raw)
In-Reply-To: <20220312102705.71413-1-Julia.Lawall@inria.fr>
Use kzalloc instead of kmalloc + memset.
The semantic patch that makes this change is:
(https://coccinelle.gitlabpages.inria.fr/website/)
//<smpl>
@@
expression res, size, flag;
@@
- res = kmalloc(size, flag);
+ res = kzalloc(size, flag);
...
- memset(res, 0, size);
//</smpl>
