linux-next: build failure after merge of the driver-core tree

[Stephen Rothwell]

Hi Greg,

After merging the driver-core tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/block/zram/zram_drv.c:1296:28: error: expected ')' before numeric constant
 static CLASS_ATTR(hot_add, 0400, hot_add_show, NULL);
                            ^
drivers/block/zram/zram_drv.c:1330:3: error: 'class_attr_hot_add' undeclared here (not in a function)
  &class_attr_hot_add.attr,
   ^
drivers/block/zram/zram_drv.c:1282:16: warning: 'hot_add_show' defined but not used [-Wunused-function]
 static ssize_t hot_add_show(struct class *class,
                ^

Caused by commit

  27104a53d02e ("zram: use class_groups instead of class_attrs")

I have reverted that commit for today (and commit

  ecbaa83ee84c ("driver core: remove class_attrs from struct class")

temporarily so the the tree will build).
