Revision aa8419367b62044e92bd7993eeb83d861b59bafa authored by Ian Kent on 11 October 2016, 20:53:02 UTC, committed by Linus Torvalds on 11 October 2016, 22:06:31 UTC 
autofs: fix dev ioctl number range check
 
The count of miscellaneous device ioctls in fs/autofs4/autofs_i.h is wrong.

The number of ioctls is the difference between AUTOFS_DEV_IOCTL_VERSION_CMD
and AUTOFS_DEV_IOCTL_ISMOUNTPOINT_CMD (14) not the difference between
AUTOFS_IOC_COUNT and 11 (21).

[kusumi.tomohiro@gmail.com: fix typo that made the count macro negative]
