The seq_printf return value will eventually be converted to void.
Convert these uses to:
seq_printf(seq, ...);
return seq_has_overflowed(seq);
Done via cocci script:
@@
struct seq_file *seq;
@@
- return
\(seq_printf\|seq_puts\|seq_putc\)(seq,
...);
+ return seq_has_overflowed(seq);
With some additional reformatting and typing post conversion
Miscellanea:
o convert an rc++ use to a bool
o use seq_puts with fixed strings where appropriate
