Subject: [PATCH 4.4 260/342] cpufreq: pxa2xx: fix pxa_cpufreq_change_voltage prototype

4.4-stable review patch.  If anyone has any objections, please let me know.


From: Arnd Bergmann <>

commit fb2a24a1c6457d21df9fae0dd66b20c63ba56077 upstream.

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.
