Subject: [PATCH 3.12 078/101] pcmcia: pxa2xx: fix logic for lubbock

From: Arnd Bergmann <arnd@...db.de>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit f1674f213ec81c55c909bb6805d3502b5883754d upstream.

The lubbock platform uses the sa1111 companion chip with a pxa250
CPU, which means it requires both the PCMCIA_SA1111 and the
PCMCIA_PXA2XX code to be built into the kernel. Unfortunately,
the Makefile and Kconfig don't agree on how this is accomplished,
leading to a situation where you get this link error when building
a lubbock kernel with PCMCIA_SA1111 enabled but PCMCIA_PXA2XX
disabled:

ERROR: "pxa2xx_configure_sockets" [drivers/pcmcia/sa1111_cs.ko] undefined!
ERROR: "pxa2xx_drv_pcmcia_ops" [drivers/pcmcia/sa1111_cs.ko] undefined!
ERROR: "pxa2xx_drv_pcmcia_add_one" [drivers/pcmcia/sa1111_cs.ko] undefined!

This patch changes the Kconfig code to disallow that particular
configuration.
