A minimum sampling rate value of 10ms was introduced in: commit cef9615a853e ("[CPUFREQ] ondemand: Uncouple minimal sampling rate from HZ in NO_HZ case") The use of this value was removed in: commit ed4676e25463 ("cpufreq: Replace "max_transition_latency" with "dynamic_switching"") Remove: - a comment referencing this value - an unused macro associated to this value Signed-off-by: Pierre Gondois <pierre.gondois@arm.com> --- drivers/cpufreq/cpufreq_ondemand.c | 1 - include/linux/cpufreq.h | 4 +--- 2 files changed, 1 insertion(+), 4 deletions(-)
