From: Max Bires Date: Tue, 3 Jan 2017 16:18:07 +0000 (-0800) Subject: char: lack of bool string made CONFIG_DEVPORT always on X-Git-Tag: v5.15~11843^2~132 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f2cfa58b136e4b06a9b9db7af5ef62fbb5992f62;p=platform%2Fkernel%2Flinux-starfive.git char: lack of bool string made CONFIG_DEVPORT always on Without a bool string present, using "# CONFIG_DEVPORT is not set" in defconfig files would not actually unset devport. This esnured that /dev/port was always on, but there are reasons a user may wish to disable it (smaller kernel, attack surface reduction) if it's not being used. Adding a message here in order to make this user visible.
