[ 029/115] usb: remove redundant tdi_reset

From: Greg Kroah-Hartman

3.9-stable review patch. If anyone has any objections, please let me know.

------------------

From: Shengzhou Liu <Shengzhou.Liu@xxxxxxxxxxxxx>

commit 61ac6ac8d662ac7ac67c864954d39d1b19948354 upstream.

We remove the redundant tdi_reset in ehci_setup since there
is already it in ehci_reset.
It was observed that the duplicated tdi_reset was causing
the PHY_CLK_VALID bit unstable.
