#     powerpc/pseries/energy: Use OF accessor functions to read ibm,drc-indexes
#     
#     In cpu_to_drc_index() in the case when FW_FEATURE_DRC_INFO is absent,
#     we currently use of_read_property() to obtain the pointer to the array
#     corresponding to the property "ibm,drc-indexes". The elements of this
#     array are of type __be32, but are accessed without any conversion to
#     the OS-endianness, which is buggy on a Little Endian OS.
#     
#     Fix this by using of_property_read_u32_index() accessor function to
#     safely read the elements of the array.
#     
#     Fixes: e83636ac3334 ("pseries/drc-info: Search DRC properties for CPU indexes")
