Dave,

these patches repair warnings seen with the linux-2.6.git 2.6.35
caused by the used constants READ / WRITE.

The patches apply on linux-2.6.git and net-next-2.6.git.

shortlog:

ctcm: rename READ/WRITE defines to avoid redefinitions

Thanks,
      Ursula

From: Heiko Carstens <heiko.carstens@de.ibm.com>

READ/WRITE seems to be a bit too generic for defines in a device driver.
Just rename them to READ_CHANNEL/WRITE_CHANNEL which should suffice.

Fixes this:

In file included from drivers/s390/net/claw.c:93:
drivers/s390/net/claw.h:78:1: warning: "WRITE" redefined
In file included from /home2/heicarst/linux-2.6/arch/s390/include/asm/debug.h:12,
                 from drivers/s390/net/claw.c:68:
include/linux/fs.h:156:1: warning: this is the location of the previous definition

[-- Type: text/plain, Size: 25838 bytes --]

From: Ursula Braun <ursula.braun@de.ibm.com>

READ/WRITE seems to be a bit too generic for defines in a device
driver. Just rename them to CTCM_READ/CTCM_WRITE to avoid warnings.
