From f0cda7e6dc5893b4b4daa3440512fc1226bc983f Mon Sep 17 00:00:00 2001 From: Luc Van Oostenryck Date: Wed, 28 Jun 2017 16:58:07 +0200 Subject: [PATCH] arm64: fix endianness annotation in acpi_parking_protocol.c Here both variables 'cpu_id' and 'entry_point' are read via read[lq]_relaxed(), from a little-endian annotated pointer and then used as a native endian value. This is correct since the read[lq]() family of function internally do a little-to-native endian conversion. But in this case, it is wrong to declare these variable as little-endian since there are native ones. Fix this by changing the declaration of these variables as 'u32' or 'u64' instead of '__le32' / '__le64'.
