From be944ceb6761a6198f5df51c36fd91eb9e112704 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Wed, 6 Sep 2023 22:00:19 +0200 Subject: [PATCH] i2c: rcar: avoid non-standard use of goto Kernel functions goto somewhere on error conditions. Using goto for the default path is irritating. Let's bail out on error instead and use a proper retval.
