A u8 is not sufficient to store the data rate, resulting in a crash due to incorrect calculations. This series resolves the issue by restoring the data type changed in commit 2589c4025f13 to their original type. Thanks to CrystalGamma for identifying the commit causing the regression. v2: Keep lane count as u8 Tobias Schramm (1): drm/rockchip: fix integer type used for storing dp data rate drivers/gpu/drm/rockchip/cdn-dp-core.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
