| |
The function using variable 'acpi_cpufreq_online' has been deleted, so it is redundant. Similarly, variable 'ret' assigned to acpi_cpufreq_online is redundant, and 'ret' is not initialized, because its assignment statement has also been eliminated.
Remove the unused variables to silence this warning: drivers/cpufreq/acpi-cpufreq.c:960:9: note: initialize the variable 'ret' to silence this warning
