X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=20634fd1cd3b004088847318024a714f17f2d975;p=linux-beck.git

[media] ddbridge: Replace vmalloc with vzalloc

vzalloc combines vmalloc and memset 0.

The Coccinelle semantic patch used to make this change is as follows:
@@
type T;
T *d;
expression e;
statement S;
@@

        d =
-            vmalloc
+            vzalloc
             (...);
        if (!d) S
-       memset(d, 0, sizeof(T));
