X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=96aa1549afa6c79ae4a4f099de861efd218c38d8;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

nfs: remove kfree() redundant null checks

smatch analysis:

fs/nfs/getroot.c:130 nfs_get_root() info: redundant null
 check on name calling kfree()

fs/nfs/unlink.c:272 nfs_async_unlink() info: redundant null
 check on devname_garbage calling kfree()
