From 21041f185015418f7a34d7789fe7850a3c4ff8f6 Mon Sep 17 00:00:00 2001 From: John Youn Date: Mon, 23 May 2016 11:32:47 -0700 Subject: [PATCH] UPSTREAM: usb: dwc3: Endianness issue on dwc3_log_ctrl Sparse complains even though it looks ok. Probably it cannot detect that the wValue, wIndex, and wLength are declared __le16 due to the macro magic. Redeclare them as CPU endianness and make the conversion on assignment.
