Subject: fs/ncpfs/inode.c: suppress used-uninitialised warning
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2a5cac17c06f897537f91f0040b3d3c8177f6433;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

fs/ncpfs/inode.c: suppress used-uninitialised warning

We get this spurious warning:

  fs/ncpfs/inode.c: In function 'ncp_fill_super':
  fs/ncpfs/inode.c:451: warning: 'data.mounted_vol[1u]' may be used uninitialized in this function
  fs/ncpfs/inode.c:451: warning: 'data.mounted_vol[2u]' may be used uninitialized in this function
  fs/ncpfs/inode.c:451: warning: 'data.mounted_vol[3u]' may be used uninitialized in this function
  ...

It's notabug, but we can easily fix it with a memset().
