From: Xenia Ragiadakou <burzalodowa@xxxxxxxxx> This patch fixes the following sparse warnings: drivers/usb/host/./xhci-trace.h:116:1: warning: cast to restricted __le32 drivers/usb/host/./xhci-trace.h:116:1: warning: cast to restricted __le32 drivers/usb/host/./xhci-trace.h:116:1: warning: restricted __le32 degrades to integer drivers/usb/host/./xhci-trace.h:116:1: warning: restricted __le32 degrades to integer by converting the field 'trb' of the trace buffer entry structure from array with elements of type __le32 to an array with elements of type u8. Into the trb array are copied the contents of the TRB that generated the event. The trace-cmd tool with the help of plugin_xhci.py will use this field to parse the TRB contents in a human readable way. This patch should be backported to kernels as old as 3.12, that contain the commit 63a23b9a7451660525c90b08219e14e701e294f1 "xhci: add xhci_cmd_completion trace event" Signed-off-by: Xenia Ragiadakou <burzalodowa@xxxxxxxxx> Signed-off-by: Sarah Sharp <sarah.a.sharp@xxxxxxxxxxxxxxx> Cc: stable@xxxxxxxxxxxxxxx --- drivers/usb/host/xhci-trace.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/usb/host/xhci-trace.h b/drivers/usb/host/xhci-trace.h index afe093340834..dde3959b7a33 100644 --- a/drivers/usb/host/xhci-trace.h +++ b/drivers/usb/host/xhci-trace.h @@ -116,7 +116,7 @@ DECLARE_EVENT_CLASS(xhci_log_event, __field(u64, dma) __field(u32, status) __field(u32, flags) - __dynamic_array(__le32, trb, 4) + __dynamic_array(u8, trb, sizeof(struct xhci_generic_trb)) ), TP_fast_assign( __entry->va = trb_va; -- 1.8.3.3 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
