Subject: [PATCH] cpufreq: powernow: Remove redundant 'ret' variable in powernow_decode_bios()

Remove the unnecessary 'ret' variable from the powernow_decode_bios()
function. It is only used once to store the return value of get_ranges(p)
before immediately returning it. Simplify the code by directly returning
the result of get_ranges(p) instead.
