+This fixes the following error when building for arm-imx:
+> ERROR: "__clk_get_name" [drivers/staging/imx-drm/ipu-v3/imx-ipu-v3.ko] undefined!
+> make[1]: *** [__modpost] Error 1
+> make: *** [modules] Error 2
+
+There are valid usecases to get the name of a clock, be it for debugging
+purposes or to register a children of a clock like done in this IPU driver.
+Therefore exporting __clk_get_name() and make it available for others makes
+sense.
