[PATCH v3 0/5] usb drivers use devm_clk_get_enabled() helpers

The devm_clk_get_enabled() helpers:
    - call devm_clk_get()
    - call clk_prepare_enable() and register what is needed in order to
     call clk_disable_unprepare() when needed, as a managed resource.

This simplifies the code and avoids calls to clk_disable_unprepare().

Fix the email thread.

version 2 changes

The files ux500.c, mpfs.c, and pxa27x_udc.c have incorrect usage of 
certain interfaces due to the lack of synchronization during the 
commit updates. These issues have been corrected in the v1 version.

1.ux500: Incorrect usage of clk_prepare_enable() should be corrected to
  devm_clk_get_enabled().
2.mpfs: Incorrect usage of devm_clk_get_enable() should be corrected to
  devm_clk_get_enabled().
3.pxa27x_udc: Incorrect usage of clk_prepare_enable() should be
  corrected to devm_clk_get_enabled().
