From 117e2cb3eeee2940ba581d104951f6207cb46ce5 Mon Sep 17 00:00:00 2001 From: Chen Zhou Date: Sat, 9 May 2020 17:18:49 +0800 Subject: sparc: use scnprintf() in show_pciobppath_attr() in vio.c snprintf() returns the number of bytes that would be written, which may be greater than the the actual length to be written. show_pciobppath_attr() should return the number of bytes printed into the buffer. This is the return value of scnprintf(). Signed-off-by: Chen Zhou Signed-off-by: David S.
