cpufreq: ACPI: Remove unused variables 'acpi_cpufreq_online' and 'ret'
Clang warns: drivers/cpufreq/acpi-cpufreq.c:970:24: error: variable 'ret' is uninitialized when used here [-Werror,-Wuninitialized] acpi_cpufreq_online = ret; ^~~ drivers/cpufreq/acpi-cpufreq.c:960:9: note: initialize the variable 'ret' to silence this warning int ret; ^ = 0 1 error generated. Both ret and acpi_cpufreq_online are now unused so they can be safely removed, clearing up the warning.
