From f2c1b4f9c15781fec5341621ce60f5cf1f2fad61 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 26 Aug 2020 13:44:59 +0300 Subject: [PATCH] driver core: Annotate dev_err_probe() with __must_check commit e1f82a0dcf388d98bcc7ad195c03bd812405e6b2 upstream. We have got already new users of this API which interpret it differently and miss the opportunity to optimize their code. In order to avoid similar cases in the future, annotate dev_err_probe() with __must_check.
