Subject: allow LEGACY_PTYS to be set to 0
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=345ee8392dc149ca529f80e40583928977ad592e;p=openwrt%2Fstaging%2Fblogic.git

allow LEGACY_PTYS to be set to 0

The count of legacy pty devices can be set by a kernel commandline
parameter. For the distro kernel, we would like to disable all pty's
by default, but keep the opportunity to request devices on the kernel
commandline.
