Commit c814bf9589 ("powerpc/selftests: Use timersub() for
gettimeofday()"), got the order of arguments to timersub() wrong,
leading to a negative time delta being reported, eg:
test: gettimeofday
tags: git_version:v6.12-rc5-409-gdddf291c3030
time = -3.297781
success: gettimeofday
The correct order is minuend, subtrahend, which in this case is end,
start. Which gives:
test: gettimeofday
tags: git_version:v6.12-rc5-409-gdddf291c3030-dirty
time = 3.300650
success: gettimeofday
Fixes: c814bf9589 ("powerpc/selftests: Use timersub() for gettimeofday()")
