[libvirt] [PATCH] nwfilter: variable 'obj' must be initialized inside nwfilterBindingCreateXML().
The function nwfilterBindingCreateXML() is failing to compile due to a
conditional branch which leads to a undefined 'obj' variable. So 'obj'
must have a initial value to avoid compilation errors. See the problem:
CC nwfilter/libvirt_driver_nwfilter_impl_la-nwfilter_driver.lo
nwfilter/nwfilter_driver.c:752:9: error: variable 'obj' is used uninitialized
whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]
if (virNWFilterBindingCreateXMLEnsureACL(conn, def) < 0)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
nwfilter/nwfilter_driver.c:779:10: note: uninitialized use occurs here
if (!obj)
^~~
nwfilter/nwfilter_driver.c:752:5: note: remove the 'if' if its condition is always
false
if (virNWFilterBindingCreateXMLEnsureACL(conn, def) < 0)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
nwfilter/nwfilter_driver.c:742:33: note: initialize the variable 'obj' to silence
this warning
virNWFilterBindingObjPtr obj;
^
= NULL
This commit initialized 'obj' with NULL to fix the error properly.
