[PATCH 6.6 06/14] thunderbolt: Use weight constants in tb_usb3_consumed_bandwidth()

From: Alexandru Gagniuc
Date: Tue Oct 01 2024 - 13:33:49 EST


From: Mika Westerberg <mika.westerberg@xxxxxxxxxxxxxxx>

[ Upstream commit 4d24db0c801461adeefd7e0bdc98c79c60ccefb0 ]

Instead of magic numbers use the constants we introduced in the previous
commit to make the code more readable. No functional changes.
