Subject: f2fs: initialize newly allocated dnode structure
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d66d1f76878fcb1e78592fe8aecd13f438d6c0d7;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

f2fs: initialize newly allocated dnode structure

This patch resolves Coverity #753112.

In practical, the existing code flow does not fall into the reported errorneous
path. But, anyway, let's avoid this for future.
