FROMLIST: usb: xhci-mtk: handle bandwidth table rollover xhci-mtk has 64 slots for periodic bandwidth calculations and each slot represents byte budgets on a microframe. When an endpoint's allocation sits on the boundary of the table, byte budgets' slot should be rolled over but the current implementation doesn't. This patch applies a 6 bits mask to the microframe index to handle its rollover 64 slots and prevent out-of-bounds array access.
