[PATCH] cpufreq: conservative: Simplify the condition of storing 'down_threshold'

From: Liao Chang
Date: Tue Sep 12 2023 - 02:12:05 EST


The governor currently checks if the input new down_threshold is less
than 100 before storing it. However, the up_threshold field of dbs_data
structure is also limited to be less than 100, so this check is
unnecessary and remove it.
