The patch titled
Subject: regulator: dbx500: remove use of seq_puts/seq_printf return value
has been removed from the -mm tree. Its filename was
regulator-dbx500-remove-use-of-seq_puts-seq_printf-return-value.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Joe Perches <joe@xxxxxxxxxxx>
Subject: regulator: dbx500: remove use of seq_puts/seq_printf return value
The seq_puts/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")
Miscellanea:
o Remove unnecessary dev_err("seq_<foo> overflow\n") messages
