This mainline commit is missing: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/net/wireless/ralink/rt2x00/rt2800lib.c?h=v6.18-rc1&id=66063033f77e10b985258126a97573f84bb8d3b4 This fix already exists in 5.15.y: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/net/wireless/ralink/rt2x00/rt2800lib.c?h=v5.15.194&id=2d3cef3d7a5df260a14a6679c4aca0c97e570ee5 …but is missing in 5.10.y.
