Subject: liblzma: Silence warnings from clang -Wconditional-uninitialized.
X-Git-Tag: v5.2.11~14
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2ca95b7cfea589fa7c79c38b99deafc44d851803;p=thirdparty%2Fxz.git

liblzma: Silence warnings from clang -Wconditional-uninitialized.

This is similar to 2ce4f36f179a81d0c6e182a409f363df759d1ad0.
The actual initialization of the variables is done inside
mythread_sync() macro. Clang doesn't seem to see that
the initialization code inside the macro is always executed.
