X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b5fc901002db0519093ec723fd98969bc03cd629;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/radeon/kms: Fix apparent typo in legacy CRTC memory bandwidth calculation. While investigating the cause of CRTC FIFO underruns, I noticed that when converting the memory bandwidth calculation from the userspace X driver code, an instance of '8.0' was apparently accidentally converted to '80'.
