Subject: [PATCH] ARM: mmp: allow platform devices with modular USB
Date: Wed, 12 Mar 2014 16:55:24 +0100	[thread overview]
Message-ID: <5101681.pZMdJoGtZk@wuerfel> (raw)

The USB host drivers need platform data to be defined on
pxa168 and pxa910, but the conditionals used in the devices.c
file only work if the drivers are built-in. This patch
fixes the definition by changing the #ifdef to #if IS_ENABLED(),
which works both for built-in and modular Kconfig symbols.

I found one specific problem using 'randconfig' builds, but
for consistency, this patch uses IS_ENABLED() for all Kconfig
symbols in these three files.
