mfd: Correct use after free for t7l66xb
The structure t7l66xb should not be freed before the subsequent references
to its fields in the arguments to clk_put. Furthermore, this structure is
allocated near the beginning of the function, and a goto to the label
err_noirq appears after a successful allocation, so it would seem that the
kfree should be moved down below this label.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression x,e;
identifier f;
iterator I;
statement S;
@@
*kfree(x);
... when != &x
when != x = e
when != I(x,...) S
*x->f
// </smpl>
