Subject: [PATCH] qemu_process: fix crash in qemuSaveImageDecompressionStart

MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit

Content-type: text/plain

Commit changing the code to allow passing NULL as @data into

qemuSaveImageDecompressionStart() was not correct as it left the

original call into the function as well.

Introduced-by: 2f3e582a1ac1008eba8d43c751cdba8712dd1614

Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=2247754
