drivers/char/tlclk.c: fix error return code
Convert a 0 error return code to a negative one, as returned elsewhere in the
function.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
identifier ret;
expression e,e1,e2,e3,e4,x;
@@
(
if (\(ret != 0\|ret < 0\) || ...) { ... return ...; }
|
ret = 0
)
... when != ret = e1
*x = \(kmalloc\|kzalloc\|kcalloc\|devm_kzalloc\|ioremap\|ioremap_nocache\|devm_ioremap\|devm_ioremap_nocache\)(...);
... when != x = e2
when != ret = e3
*if (x == NULL || ...)
{
... when != ret = e4
* return ret;
}
// </smpl>
