interconnect: qcom: Ensure that the floor bandwidth value is enforced
Take into account the initial bandwidth from the framework and update the internal sum and max values before committing if needed. This will ensure that the floor bandwidth values are enforced until the providers get into sync state. Fixes: 7d3b0b0d8184 ("interconnect: qcom: Use icc_sync_state") Tested-by: Akash Asthana <akashast@codeaurora.org> Link: https://lore.kernel.org/r/20201021155938.9223-1-georgi.djakov@linaro.org Signed-off-by: Georgi Djakov <georgi.djakov@linaro.org>
