Subject: [PATCH] aic7xxx/aic7770 : Use kstrdup
Date: Tue, 10 Jun 2014 19:50:37 +0530 [thread overview]
Message-ID: <20140610142037.GA2993@himangi-Dell> (raw)
Use kstrdup when the goal of an allocation is copy a string into the
allocated region.
The semantic patch that makes this change is as follows:
// <smpl>
@@
expression from,to;
expression flag,E1,E2;
statement S;
@@
- to = kmalloc(strlen(from) + 1,flag);
+ to = kstrdup(from, flag);
... when != \(from = E1 \| to = E1 \)
if (to==NULL || ...) S
... when != \(from = E2 \| to = E2 \)
- strcpy(to, from);
// </smpl>
