Subject: linux-next: build failure after merge of the final tree (char-misc
 tree related)

Hi all,

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

drivers/iio/adc/men_z188_adc.c: In function 'z188_iio_read_raw':
drivers/iio/adc/men_z188_adc.c:61:3: error: implicit declaration of function 'readw' [-Werror=implicit-function-declaration]
   tmp = readw(adc->base + chan->channel * 4);
   ^
drivers/iio/adc/men_z188_adc.c: In function 'men_z188_config_channels':
drivers/iio/adc/men_z188_adc.c:91:2: error: implicit declaration of function 'readl' [-Werror=implicit-function-declaration]
  ctl = readl(addr + Z188_CTRL_REG);
  ^
drivers/iio/adc/men_z188_adc.c:93:2: error: implicit declaration of function 'writel' [-Werror=implicit-function-declaration]
  writel(ctl, addr + Z188_CTRL_REG);
  ^
drivers/iio/adc/men_z188_adc.c: In function 'men_z188_probe':
drivers/iio/adc/men_z188_adc.c:126:2: error: implicit declaration of function 'ioremap' [-Werror=implicit-function-declaration]
  adc->base = ioremap(mem->start, resource_size(mem));
  ^
drivers/iio/adc/men_z188_adc.c:126:12: warning: assignment makes pointer from integer without a cast [enabled by default]
  adc->base = ioremap(mem->start, resource_size(mem));
            ^
drivers/iio/adc/men_z188_adc.c: In function 'men_z188_remove':
drivers/iio/adc/men_z188_adc.c:148:2: error: implicit declaration of function 'iounmap' [-Werror=implicit-function-declaration]
  iounmap(adc->base);
  ^

Caused by commit 74aeac4da66f ("iio: adc: Add MEN 16z188 ADC driver")
from the char-misc tree.  Need to include linux/io.h, I think.

I have reverted that commit for today.
