[Qemu-trivial] [PATCH v2 0/4] 3 easy-to-fix clang warnings, 1 error code

From: Philippe Mathieu-Daudé
Subject: [Qemu-trivial] [PATCH v2 0/4] 3 easy-to-fix clang warnings, 1 error code fixed
Date: Fri, 7 Apr 2017 19:20:12 -0300

This patchset fixes three easy-to-fix unrelated clang warnings, so it was
probably better to send them separately the first time.

    - hw/usb/dev-smartcard-reader.c: The first patch was treating NULL and 0 as
      errors but those values are legal in some cases, i.e. no (virtual)
      smartcard inserted into the card reader (Gerd Hoffmann's review).
    - device_tree.c: Added Marc-André Lureau's Reviewed-by.
    - qga/commands-posix.c: Added a commit to improve failed operation, as
      suggested by Michael Roth.

Philippe Mathieu-Daudé (4):
  usb-ccid: make ccid_write_data_block() cope with null buffers
  device_tree: fix compiler warnings (clang 5)
  qga: fix compiler warnings (clang 5)
  qga: improve error handling in transfer_memory_block

 device_tree.c                 |  1 +
 hw/usb/dev-smartcard-reader.c |  5 ++++-
 qga/commands-posix.c          | 11 ++++++++---
