SERIAL: ioc3_serial: Return -ENOMEM on memory allocation failure

2010-10-19T17:32:40Z

In this code, 0 is returned on memory allocation failure, even though other failures return -ENOMEM or other similar values. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @@ expression ret; expression x,e1,e2,e3; @@ ret = 0 ... when != ret = e1 *x = \(kmalloc\|kcalloc\|kzalloc\)(...) ... when != ret = e2 if (x == NULL) { ... when != ret = e3 return ret; } // Signed-off-by: Julia Lawall To: Pat Gefre Cc: kernel-janitors@vger.kernel.org Cc: linux-ia64@vger.kernel.org Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/1704/ Signed-off-by: Ralf Baechle
