From 5d8cbf7176a427cd904eaa6efdaf6960d717b0de Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 28 Jun 2019 09:20:37 -0300 Subject: docs: extcon: convert it to ReST and move to ACPI dir The intel-int3496.txt file is a documentation for an ACPI driver. There's no reason to keep it on a separate directory. So, instead of keeping it on some random location, move it to a sub-directory inside the ACPI documentation dir, renaming it to .rst.
