From 400b7f6d1465815cc3992c009caa760a668928e5 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Wed, 8 Sep 2021 16:43:57 +0100 Subject: [PATCH] linux-user: Fix coding style nits in qemu.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We're about to move a lot of the code in qemu.h out into different header files; fix the coding style nits first so that checkpatch is happy with the pure code-movement patches. This is mostly block-comment style but also a few whitespace issues.
