typedef is not really useful here. Replace it by structure
to improve readability.typedef should only be used in some cases.
(See Documentation/CodingStyle Chapter 5 for details).

AFAICS yes but this needs some fixes:
drivers/cpufreq/pxa2xx-cpufreq.c: In function 'find_freq_tables':
drivers/cpufreq/pxa2xx-cpufreq.c:218:15: warning: assignment discards 'const'
qualifier from pointer target type
*pxa_freqs = pxa255_run_freqs;
^
Maybe another patch ?
