My other patchset which fixes bugs here, could go in before: https://lore.kernel.org/all/20240814195823.437597-1-krzysztof.kozlowski@linaro.org/ so it will be backported. Other than that, I am fine with rebasing my changes. There is no point in refactoring the code if it is being removed/reshuffled :) Best regards, Krzysztof

It may make sense to push them for 6.11-rc even. > so it will be backported. Other than that, I am fine with rebasing my > changes.
