[PATCH] clk: Export clk_register_composite() for mediatek's clock kernel module

[Wendell Lin]

This series based on 5.8-rc1
This patch exports clk_register_composite() and common APIs from
Mediatek clock driver. clk_register_composite() will be used in
mediatek's clock kernel module, so export it to GPL modules.

Wendell Lin (2):
  clk: Export clk_register_composite
  clk: mediatek: Add EXPORT_SYMBOL for kernel module support

Is this needed for something? I'd prefer to see some sort of mediatek
modular patches that included this patch in it before this is applied.

Got it. 
I'll prepare a new series of mediatek modular patches that included this
patch in it later.
