Subject: [Qemu-devel] [PATCH] crypto: move 'opaque' parameter to (nearly) the end of parameter list
Date: Mon, 24 Apr 2017 16:36:15 +0100 [thread overview]
Message-ID: <20170424153615.18614-1-berrange@redhat.com> (raw)
Previous commit moved 'opaque' to be the 2nd parameter in the list:
commit 375092332eeaa6e47561ce47fd36144cdaf964d0
Author: Fam Zheng <famz@redhat.com>
Date: Fri Apr 21 20:27:02 2017 +0800
crypto: Make errp the last parameter of functions
Move opaque to 2nd instead of the 2nd to last, so that compilers help
check with the conversion.
this puts it back to the 2nd to last position.
