From 8e22978c57087aac4d88693278db1cc3e94f1253 Mon Sep 17 00:00:00 2001 From: Alexander Shishkin Date: Mon, 24 Jun 2013 14:46:36 +0300 Subject: usb: chipidea: drop "13xxx" infix "ci13xxx" is bad for at least the following reasons: * people often mistype it * it doesn't add any informational value to the names it's used in * it needlessly attracts mail filters This patch replaces it with "ci_hdrc", "ci_udc" or "ci_hw", depending on the situation. Modules with ci13xxx prefix are also renamed accordingly and aliases are added for compatibility. Otherwise, no functional changes.
