Subject: s390: remove use of seq_printf return value
X-Git-Tag: v4.1-rc1~115^2~5
X-Git-Url: https://git.kernel.dk/?p=linux-2.6-block.git;a=commitdiff_plain;h=c2f0b61d8969adf0dfb11aea7b700740fde6420b

s390: remove use of seq_printf return value

The seq_printf return value, because it's frequently misused,
will eventually be converted to void.

See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to
     seq_has_overflowed() and make public")
