ipr: Endian / sparse fixes
Browse files Browse the repository at this point in the history
Some misc fixes for endianness checking with sparse so sparse with
endian checking now runs clean. Fixes a minor bug in the process
which was uncovered by sparse which would result in unnecessary
error recovery for check conditions.
