From 59d84ca8c46a93ad62f9129458e897e7fe5075de Mon Sep 17 00:00:00 2001 From: Quentin Lambert Date: Mon, 9 Feb 2015 10:45:32 +0100 Subject: [PATCH] PM / OPP / clk: Remove unnecessary OOM message This patch reduces the kernel size by removing error messages that duplicate the normal OOM message. A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr) @@ identifier f,print,l; expression e; constant char[] c; @@ e = \(kzalloc\|kmalloc\|devm_kzalloc\|devm_kmalloc\)(...); if (e == NULL) { <+... - print(...,c,...); ... when any ( goto l; | return ...; ) ...+> } Signed-off-by: Quentin Lambert Acked-by: Nishanth Menon Signed-off-by: Rafael J.
