From 7895861a963cfa995f4233e83665563ab404f73e Mon Sep 17 00:00:00 2001 From: Jordan Crouse Date: Mon, 26 Nov 2018 10:20:31 -0700 Subject: [PATCH] clk: qcom: gdsc: Don't override existing gdsc pd functions In extreme cases an individual gdsc may wish to override the power domain enable or disable callback functions for their own purposes. Only set the generic gdsc callback if the function pointers are not already set.
