That's because you have to remove from magician.c: pxa_set_stuart_info(NULL); Cheers. -- Robert [1] >From ea242c5b1c4dcdf2a99ea604ee542ded5e6384b9 Mon Sep 17 00:00:00 2001 From: Robert Jarzmik <robert.jarz...@free.fr> Date: Sat, 29 Aug 2015 00:37:51 +0200 Subject: [PATCH] ARM: pxa: add resources to pxaficp_ir Add io memory and dma requestor lines to the irda pxa device. This is part of the conversion of pxaficp_ir to dmaengine, and to shrink its adherence to 'mach' includes.
