Subject: [PATCH] pcmcia: m8xx: remove checks for four macros

From: Paul Bolle <[email-masked]>
Date: Sat, 24 May 2014 09:36:10 +0200

This driver contains checks for four Kconfig macros. But the related
Kconfig symbols have never been part of the tree. Remove these checks
and the code they hide.

Untested.

This has been an issue ever since this driver was added in v2.6.15. Note
that there is no header named "*/cpld.h", so setting PRxK can't possibly
work.
