commit f5c5426924c25df4c16018cfca752963e982f485 Author: Thomas Faber <[email protected]> AuthorDate: Thu Nov 25 09:30:03 2021 -0500 Commit: Thomas Faber <[email protected]> CommitDate: Thu Feb 17 22:01:34 2022 -0500 [USBPORT] Fix incorrect use of bitfields. EndpointMoved == TRUE could never be true, because BOOL is a signed type, and the only two values in a signed one-bit type are 0 and -1. Courtesy of VS analysis warning C6299: Explicitly comparing a bit field to a Boolean type will yield unexpected results. --- drivers/usb/usbport/usb2.c | 4 ++-- drivers/usb/usbport/usbport.h | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/drivers/usb/usbport/usb2.c b/drivers/usb/usbport/usb2.c index 1d609addaa7..9d7a6548bc1 100644 --- a/drivers/usb/usbport/usb2.c +++ b/drivers/usb/usbport/usb2.c @@ -644,7 +644,7 @@ USB2_MoveTtEndpoint(IN PUSB2_TT_ENDPOINT TtEndpoint, TransferType = TtEndpoint->TtEndpointParams.TransferType; if (Rebalance->RebalanceEndpoint[Num] && - TtEndpoint->TtEndpointParams.EndpointMoved == TRUE && + TtEndpoint->TtEndpointParams.EndpointMoved && ((TransferType != USBPORT_TRANSFER_TYPE_INTERRUPT) || BusTime >= 0)) { DPRINT("USB2_MoveTtEndpoint: result - FALSE\n"); @@ -668,7 +668,7 @@ USB2_MoveTtEndpoint(IN PUSB2_TT_ENDPOINT TtEndpoint, *OutResult = FALSE; } - TtEndpoint->TtEndpointParams.EndpointMoved = TRUE; + TtEndpoint->TtEndpointParams.EndpointMoved = 1; if (Rebalance->RebalanceEndpoint[Num] == NULL) { diff --git a/drivers/usb/usbport/usbport.h b/drivers/usb/usbport/usbport.h index 04936bfe304..02726fea48c 100644 --- a/drivers/usb/usbport/usbport.h +++ b/drivers/usb/usbport/usbport.h @@ -486,8 +486,8 @@ typedef union _USB2_TT_ENDPOINT_PARAMS { struct { ULONG TransferType : 4; ULONG Direction : 1; - USB_DEVICE_SPEED DeviceSpeed : 2; - BOOL EndpointMoved : 1; + ULONG DeviceSpeed : 2; + ULONG EndpointMoved : 1; ULONG Reserved : 24; }; ULONG AsULONG;
