Subject: linux-next: trivial tree build failure

Hi Jiri,

Today's linux-next build (x86_64_allmodconfig) failed like this:

drivers/mfd/ab3100-otp.c: In function 'show_otp':
drivers/mfd/ab3100-otp.c:101: error: dereferencing pointer to incomplete type
drivers/mfd/ab3100-otp.c:104: error: implicit declaration of function 'seq_printf'

Exposed by commit 8dcafdf0475eb4633401d1f0bf0e0d35e4ebb9d5
"CONFIG_DEBUG_FS wrongly written as CONFIG_DEBUGFS".

I have reverted that commit for today.

That file probably just needs to include <linux/seq_file.h> ...
