Subject: NFSD: Remove setting unused variable in nfsd_vfs_read()
X-Git-Tag: v3.0-rc1~8^2~3
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fccb13c947de83a368e1f3c2216bbf4d8d41efa1;p=karo-tx-linux.git

NFSD: Remove setting unused variable in nfsd_vfs_read()

Compiling gave me this warning:
fs/nfsd/vfs.c: In function ‘nfsd_vfs_read’:
fs/nfsd/vfs.c:880:16: warning: variable ‘inode’ set but not used
[-Wunused-but-set-variable]

I discovered that a local variable "inode" was being set towards the
beginning of nfsd_vfs_read() and then ignored for the rest of the
function.
