All warnings (new ones prefixed by >>, old ones prefixed by <<):

>> WARNING: modpost: vmlinux.o(.text+0xb94): Section mismatch in reference from the function regulator_set_voltage_sel_regmap() to the function .init.text:alloc_tree_node()
The function regulator_set_voltage_sel_regmap() references
the function __init alloc_tree_node().
This is often because regulator_set_voltage_sel_regmap lacks a __init
annotation or the annotation of alloc_tree_node is wrong.
