[PATCH 23/27] drm/amd/display: fix dml log2 function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dmytro Laktyushkin <Dmytro.Laktyushkin@xxxxxxx>

This change removes internal rounding in dml_log2 function.

Dml_log2 is expected to return a float output. In case an int is needed
dml will floor the output on it's own.
