From 4b49df654cd0d1c3c359fc0f52182943a650b746 Mon Sep 17 00:00:00 2001 From: Chen Jiahao Date: Wed, 26 Jul 2023 10:17:59 +0000 Subject: [PATCH] samples/hw_breakpoint: mark sample_hbp as static There is a sparse warning shown as below: samples/hw_breakpoint/data_breakpoint.c:24:19: warning: symbol 'sample_hbp' was not declared. Should it be static? Since 'sample_hbp' is only called within data_breakpoint.c, mark it as static to fix the warning.
