cpufreq: pxa2xx: fix pxa_cpufreq_change_voltage prototype
There are two definitions of pxa_cpufreq_change_voltage, with slightly different prototypes after one of them had its argument marked 'const'. Now the other one (for !CONFIG_REGULATOR) produces a harmless warning: drivers/cpufreq/pxa2xx-cpufreq.c: In function 'pxa_set_target': drivers/cpufreq/pxa2xx-cpufreq.c:291:36: warning: passing argument 1 of 'pxa_cpufreq_change_voltage' discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers] ret = pxa_cpufreq_change_voltage(&pxa_freq_settings[idx]); ^ drivers/cpufreq/pxa2xx-cpufreq.c:205:12: note: expected 'struct pxa_freqs *' but argument is of type 'const struct pxa_freqs *' static int pxa_cpufreq_change_voltage(struct pxa_freqs *pxa_freq) ^ This changes the prototype in the same way as the other, which avoids the warning.
