From: Greg Kroah-Hartman gregkh@linuxfoundation.org
In commit d951cf510fb0 ("cpufreq: brcmstb-avs-cpufreq: add check for cpufreq_cpu_get's return value"), build warnings occur because a variable is created after some logic, resulting in:
drivers/cpufreq/brcmstb-avs-cpufreq.c: In function 'brcm_avs_cpufreq_get': drivers/cpufreq/brcmstb-avs-cpufreq.c:486:9: error: ISO C90 forbids mixed declarations and code [-Werror=declaration-after-statement] 486 | struct private_data *priv = policy->driver_data; | ^~~~~~ cc1: all warnings being treated as errors make[2]: *** [scripts/Makefile.build:289: drivers/cpufreq/brcmstb-avs-cpufreq.o] Error 1 make[1]: *** [scripts/Makefile.build:552: drivers/cpufreq] Error 2 make[1]: *** Waiting for unfinished jobs.... make: *** [Makefile:1907: drivers] Error 2
Fix this up.
