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 <lambert.quentin@gmail.com> Acked-by: Nishanth Menon <nm@ti.com> Signed-off-by: Rafael J.
