Subject: Fix uninitialised read in fuse_new_30() (#231) (#234)
X-Git-Tag: fuse-3.2.2~3
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=03515bbb3092da9b3c2c6a267de90f9f0dcbdb29;p=qemu-gpiodev%2Flibfuse.git

Fix uninitialised read in fuse_new_30() (#231) (#234)

Ensure that conf is always zero before it's read from to prevent
sporadic failure at startup if higher layers were build against
version 3.0
