Subject: [PATCH] ipmi: Remove incorrect use of seq_has_overflowed
commit d6c5dc18d863 ("ipmi: Remove uses of return value of seq_printf")
incorrectly changed the return value of various proc_show functions
to use seq_has_overflowed().
These functions should return 0 on completion rather than 1/true
on overflow. 1 is the same as #define SEQ_SKIP which would cause
the output to not be emitted (skipped) instead.
This is a logical defect only as the length of these outputs are
all smaller than the initial allocation done by the seq filesystem.
