Subject: usb: chipidea: drop "13xxx" infix
X-Git-Tag: firefly_0821_release~176^2~5847^2~10
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=8e22978c57087aac4d88693278db1cc3e94f1253;p=firefly-linux-kernel-4.4.55.git

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.
