Subject: Revert "USB: serial: sierra: put reset_resume callback back."
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0b623f871d7c993fac8ad7aaaa8f5f3cdb8ed480;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Revert "USB: serial: sierra: put reset_resume callback back."

This reverts commit 6971113e1000d24f7d4975eaa6f8cf2739a4565b.

As Alan pointed out, this really isn't needed as it doesn't handle this
properly.  Ideally this should be handled by the usb-serial core one
day.  So revert it.
