If anyone has any objections, please let me know. ------------------ [ Upstream commit 8927c27b32703e28041ae19bf25ea53461be83a1 ] When building armada-37xx-periph, num_parents isn't used in function clk_pm_cpu_get_parent: drivers/clk/mvebu/armada-37xx-periph.c: In function ‘clk_pm_cpu_get_parent’: drivers/clk/mvebu/armada-37xx-periph.c:419:6: warning: unused variable ‘num_parents’ [-Wunused-variable] int num_parents = clk_hw_get_num_parents(hw); ^~~~~~~~~~~ Remove the declaration of num_parents to dispose the warning.
