Subject: linux-next: build failure after merge of the i2c tree

Hi Wolfram,

After merging the i2c tree, today's linux-next build (powerpc
ppc44x_defconfig) failed like this:

drivers/i2c/busses/i2c-ibm_iic.c:102:15: error: redefinition of 'struct i2c_timings'
 static struct i2c_timings {
               ^
In file included from drivers/i2c/busses/i2c-ibm_iic.c:42:0:
include/linux/i2c.h:424:8: note: originally defined here
 struct i2c_timings {
        ^

Caused by commit

  e1dba01ca620 ("i2c: add generic routine to parse DT for timing information")

I have applied the following patch for today:

From: Stephen Rothwell <sfr@...b.auug.org.au>
