Subject: Support Linux kernel earilier version than v4.9
X-Git-Tag: accepted/tizen/unified/20201222.122620~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6af6d40a3d31096d83eb6f7bdd9194ac64e2ef03;p=platform%2Fcore%2Fsystem%2Fstability-monitor-kmod-rpi3.git

Support Linux kernel earilier version than v4.9

From Linux kernel v4.9, seq_put_decimal_ll() changes its delimiter
argument to const char * instead of char. Support older version.
