+Subject: udf: initialize newblock to 0
+
+From: Tom Rix <trix@redhat.com>
+
+commit 23970a1c9475b305770fd37bebfec7a10f263787 upstream.
+
+The clang build reports this error
+fs/udf/inode.c:805:6: error: variable 'newblock' is used uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]
+        if (*err < 0)
+            ^~~~~~~~
+newblock is never set before error handling jump.
+Initialize newblock to 0 and remove redundant settings.
+
+Fixes: d8b39db5fab8 ("udf: Handle error when adding extent to a file")
