[PATCH 1/2] tty: ldisc: Fix misuse of proc_dointvec "ldisc_autoload"

From: Eiichi Tsukata
Date: Mon Jun 24 2019 - 23:08:20 EST


/proc/sys/dev/tty/ldisc_autoload assumes given value to be 0 or 1. Use
proc_dointvec_minmax instead of proc_dointvec.

Fixes: 7c0cca7c847e "(tty: ldisc: add sysctl to prevent autoloading of ldiscs)"
