Subject: [PATCH] aic7xxx/aic79xx : Use kstrdup
Date: Tue, 10 Jun 2014 19:54:30 +0530	[thread overview]
Message-ID: <20140610142430.GA3048@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>
