Umm, this won't compile. seq_puts() is defined as:

  int seq_puts(struct seq_file *m, const char *s);

checkpatch.pl does indeed complain about uses of seq_printf() in
drivers/staging/android/binder.c which are passing formatted strings. At
a quick glance it looks like checkpatch.pl is only checking for the
format string on the same line as seq_printf(), so this files ugly
coding style confuses the check. Joe?

Anyway, please don't blindly change things in the kernel without at
least compile testing them.
