[PATCH][next] rocker: fix kcalloc parameter order

[PATCH][next] rocker: fix kcalloc parameter order

[Zahari Doychev]

The function calls to kcalloc use wrong parameter order. The flags
have to be passed as last parameter.

The change was done using the following coccinelle script:

@@
expression E1,E2;
type T;
@@

-kcalloc(E1, E2, sizeof(T))
+kcalloc(E2, sizeof(T), E1)

I think that the flags are also not used correctly, so I will have to resend
the patch.
