[Qemu-block] [PATCH 01/13] ide: move headers to include folder |
|
Date: |
Fri, 17 Jun 2016 16:10:57 +0300 |
The patch moves "hw/ide/achi.h", "hw/ide/pci.h" and "hw/ide/internal.h" headers
to corresponding folders inside "include" folder alike other Qemu headers.
Signed-off-by: Efimov Vasily <address@hidden>

This patch only moves headers (with the exception of include path correction
in 'ahci.c'). checkpatch.pl reports a lot of problems with legacy code in
these headers but I think this patch is not the place to fix these problem
