Subject: usb-mtp: change default to success for usb_mtp_update_object
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=83c44b44d406326117ca2f040bae8d7de97b9c8e;p=qemu.git

usb-mtp: change default to success for usb_mtp_update_object

Commit c5ead51f90cf (usb-mtp: return incomplete transfer on a lstat
failure) checks if lstat succeeded when updating attributes of a
file. However, it also changed behavior to return an error by
default. This is incorrect because for smaller file sizes, Qemu
will attempt to write the file in one go and there won't be
an object for it.
