From f8f02d5c671f79c4e80acbd0fca324566968cea8 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 18 Jun 2020 11:43:00 +0200 Subject: [PATCH] USB: OTG: rename product list of devices MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Rename the list of specific devices that an OTG device could support to make it more obvious as to what this list is for and what it is doing. Also rename the configuration option to make it more obvious as well. Cc: Thomas Bogendoerfer Cc: Paul Burton Cc: "Diego Elio Pettenò" Cc: "Martin K.
