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

Hi all,

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

drivers/misc/mic/host/mic_main.c: In function 'mic_probe':
drivers/misc/mic/host/mic_main.c:320:3: error: too many arguments to function 'sysfs_get_dirent'
   NULL, "state");
   ^
In file included from include/linux/kobject.h:21:0,
                 from include/linux/module.h:16,
                 from drivers/misc/mic/host/mic_main.c:26:
include/linux/sysfs.h:465:1: note: declared here
 sysfs_get_dirent(struct sysfs_dirent *parent_sd, const unsigned char *name)
 ^

Caused by commit 3a6a9201897c ("Intel MIC Host Driver, card OS state
management") interacting with commit 388975cccaaf ("sysfs: clean up
sysfs_get_dirent()") from the driver-core tree.

I added this merge fix patch:
