Subject: nvme-rdma: initialize ret to zero to avoid returning garbage
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=39bbee4e549fbc358b2ef9137c4bf459abd164fb;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

nvme-rdma: initialize ret to zero to avoid returning garbage

ret is not initialized so it contains garbage.  Ensure garbage
is not returned by initializing rc to 0.
