Subject: nfs: Fix use of uninitialized variable in nfs_getattr()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=16caf5b6101d03335b386e77e9e14136f989be87;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

nfs: Fix use of uninitialized variable in nfs_getattr()

Variable 'err' needn't be initialized when nfs_getattr() uses it to
check whether it should call generic_fillattr() or not. That can result
in spurious error returns. Initialize 'err' properly.
