From 4e5e8de0dbdeb08df2b4c15fa2b0ba2216091793 Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 24 Apr 2008 15:28:11 +0100 Subject: [ARM] pxa: avoid kfreeing static data if platform device fails to register When a dynamically allocated platform device is 'put', the platform device's platform_data is kfree'd. This is bad if it's pointing at static data. Use the provided function to register platform data for these devices. This also means we can mark the pcmcia ops structures as __initdata.
