From 8496ecd0bed4c70b43f39cecf0872b84360f0d14 Mon Sep 17 00:00:00 2001 From: Valdis Kletnieks Date: Thu, 7 Mar 2019 16:29:06 -0800 Subject: [PATCH] init/calibrate.c: provide proper prototype Sparse issues a warning: CHECK init/calibrate.c init/calibrate.c:271:28: warning: symbol 'calibration_delay_done' was not declared. Should it be static? The actual issue is that it's a __weak symbol that archs can override (in fact, ARM does so), but no prototype is provided. Let's provide one to prevent surprises.
