From 5302d1a06a2cd9855378122a07c9e0942f0f04a9 Mon Sep 17 00:00:00 2001 From: Rodrigo Siqueira rodrigo.siqueira@amd.com Date: Thu, 4 Jul 2024 11:54:34 -0600 Subject: [PATCH] drm/amd/display: Remove ASSERT if significance is zero in math_ceil2

In the DML math_ceil2 function, there is one ASSERT if the significance is equal to zero. However, significance might be equal to zero sometimes, and this is not an issue for a ceil function, but the current ASSERT will trigger warnings in those cases. This commit removes the ASSERT if the significance is equal to zero to avoid unnecessary noise.
