Subject: tests: virpcimock: Always declare __open_2
X-Git-Tag: v5.7.0-rc1~221
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=52dad8c9b0d3a008f21c082c7fd3343fdb66fffe;p=thirdparty%2Flibvirt.git

tests: virpcimock: Always declare __open_2

In some cases e.g. with clang on fedora 30 __open2 isn't even declared
which results in the following build error:

/home/pipo/libvirt/tests/virpcimock.c:939:1: error: no previous prototype for function
      '__open_2' [-Werror,-Wmissing-prototypes]
__open_2(const char *path, int flags)

Add a separate declaration to appease the compiler.
