| H A D | target_core_configfs.c | 37bb7899 Mon Sep 17 13:05:33 CDT 2012 Peter Senna Tschudin <peter.senna@gmail.com> target: fix return code in target_core_init_configfs error path
This patch fixes error cases within target_core_init_configfs() to
properly set ret = -ENOMEM before jumping to the out_global exception
path.
This was originally discovered with the following Coccinelle semantic
match information:
Convert a nonnegative 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>
(
if@p1 (\(ret < 0\|ret != 0\))
{ ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
when != &ret
*if(...)
{
... when != ret = e2
when forall
return ret;
}
// </smpl>
