+Subject: [PATCH] utils: Use name of the first prerequisite in rule
+
+Use $< instead of $^ because the latter will specify both pre-requisite
+inputattach.c serio-ids.h files on same compiler cmdline and clang does
+not like that and errors out like below
+
+clang-14: error: cannot specify -o when generating multiple output files
+
+Upstream-Status: Pending
