ipq806x: fix uninitialized variable usage in cpufreq-krait
In krait_cpufreq_probe, both freq and max_cpu_freq are never initialized, so the max_cpu_freq will have a random value at the end. Fix this by properly initializing max_cpu_freq to 0 and storing the clk frequency in freq as well, to make it similar to how it's calculated in krait_set_target. Fixes the following warnings: In file included from include/linux/clk.h:16:0, from drivers/cpufreq/cpufreq-krait.c:13: drivers/cpufreq/cpufreq-krait.c: In function 'krait_cpufreq_probe': include/linux/kernel.h:714:24: warning: 'freq' may be used uninitialized in this function [-Wmaybe-uninitialized] _max1 > _max2 ? _max1 : _max2; }) ^ drivers/cpufreq/cpufreq-krait.c:217:25: note: 'freq' was declared here unsigned long freq_Hz, freq, max_cpu_freq; ^ In file included from include/linux/clk.h:16:0, from drivers/cpufreq/cpufreq-krait.c:13: include/linux/kernel.h:714:24: warning: 'max_cpu_freq' may be used uninitialized in this function [-Wmaybe-uninitialized] _max1 > _max2 ? _max1 : _max2; }) ^ drivers/cpufreq/cpufreq-krait.c:217:31: note: 'max_cpu_freq' was declared here unsigned long freq_Hz, freq, max_cpu_freq; Signed-off-by: Jonas Gorski <jogo@openwrt.org> SVN-Revision: 46839
