From 088f8a2396d813e7ee49272a1a59b55139c81e64 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Mon, 1 Feb 2021 17:26:07 -0600 Subject: net: ipa: be explicit about endianness Sparse warns that the assignment of the metadata mask for a QMAP endpoint in ipa_endpoint_init_hdr_metadata_mask() is a bad assignment. We know we want the mask value to be big endian, even though the value we write is in host byte order. Use a __force tag to indicate we really mean it.
