[PATCH 1/3 v2] char: group dev configs togther
From: Randy Dunlap
Date: Wed Mar 11 2020 - 18:57:44 EST
Group /dev/{mem,kmem,nvram,raw,port} driver configs together.
This also means that tty configs are now grouped together instead
of being split up.
This just moves Kconfig lines around. There are no other changes.
