Subject: amdgpu/vce3: Simplify vce_v3_0_hw_init and ensure both rings default to not ready.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=691ca86a3a15a9c5054edb3c517a1aeb40e9fadc;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

amdgpu/vce3: Simplify vce_v3_0_hw_init and ensure both rings default to not ready.

Simplified the ring test and added logic to ensure rings are marked not ready
by default.
