Subject: ARM: pxa/colibri: don't register pxa2xx-pcmcia nodes on non-colibri platforms
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8d9bd9002dc8c3a05e11c5f40d95d06e15e83f71;p=linux-beck.git

ARM: pxa/colibri: don't register pxa2xx-pcmcia nodes on non-colibri platforms

PXA supports multi-machine kernels since long ago. However a kernel
compiled with support for colibri and any other PXA machine and with
PCMCIA enabled will barf at runtime about duplicate registration of
pxa2xx-pcmcia device. Fix that.
