The ibm,drc-info property is an array property that contains drc-info entries such that each entry is made up of 2 string encoded elements followed by 5 int encoded elements. The of_read_drc_info_cell() helper contains comments that correctly name the expected elements and their encoding. However, the usage of of_prop_next_string() and of_prop_next_u32() introduced a subtle skippage of the first u32. This is a result of of_prop_next_string() returning a pointer to the next property value which is not a string, but actually a (__be32 *). As, a result the following call to of_prop_next_u32() passes over the current int encoded value and actually stores the next one wrongly. Simply endian swap the current value in place after reading the first two string values. The remaining int encoded values can then be read correctly using of_prop_next_u32().
