drivers/cpufreq/pcc-cpufreq.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> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Rafael J.
