UPSTREAM: char: lack of bool string made CONFIG_DEVPORT always on

2017-04-25T09:28:21+00:00

(cherry pick from commit f2cfa58b136e4b06a9b9db7af5ef62fbb5992f62) 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.

UPSTREAM: char: Drop bogus dependency of DEVPORT on !M68K

2017-04-25T09:28:21+00:00

(cherry pick from commit 309124e2648d668a0c23539c5078815660a4a850) According to full-history-linux commit d3794f4fa7c3edc3 ("[PATCH] M68k update (part 25)"), port operations are allowed on m68k if CONFIG_ISA is defined. However, commit 153dcc54df826d2f ("[PATCH] mem driver: fix conditional on isa i/o support") accidentally changed an "||" into an "&&", disabling it completely on m68k. This logic was retained when introducing the DEVPORT symbol in commit 4f911d64e04a44c4 ("Make /dev/port conditional on config symbol"). Drop the bogus dependency on !M68K to fix this.
