[PATCH 3/3] mfd/omap-usb-tll: Return an error code only as a constant in usbtll_omap_probe()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Mon, 15 Jan 2018 14:00:45 +0100

* Return an error code without storing it in an intermediate variable.

* Delete the label "err_clk_alloc" and local variable "ret"
  which became unnecessary with this refactoring.
