Subject: net/caif: Use kzalloc
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=49afa55b5bd792cda4fca15d3238e9b6f370c856;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

net/caif: Use kzalloc

Use kzalloc rather than the combination of kmalloc and memset.

A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression x,size,flags;
statement S;
@@

-x = kmalloc(size,flags);
+x = kzalloc(size,flags);
 if (x == NULL) S
-memset(x, 0, size);
// </smpl>
