[PATCH 6.6 507/538] thunderbolt: Use weight constants in tb_usb3_consumed_bandwidth()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

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.
