[PATCH 0/7] seq_printf cleanups

[Joe Perches]

seq_printf should return void.

Add a public bool seq_is_full function that can be used to shortcut
unnecesary seq_printf/seq_puts calls when the seq buffer is full.

Start removing the misuses of the seq_printf/seq_puts return value.

Patchset brought forward from an unreplied to set of changes from
back in December 2013.

Renamed seq_is_buf_full to seq_is_full.

Joe Perches (7):
  seq_file: Rename static bool seq_overflow to public bool seq_is_full
  netfilter: Convert print_tuple functions to return void
  dlm: Use seq_is_full - remove seq_printf returns
  dlm: Use seq_puts, remove unnecessary trailing spaces
  fs: Convert show_fdinfo functions to void
  debugfs: Fix misuse of seq_printf return value
  docg3: Fix mixuse of seq_printf return value
