From ce62df2290bb86b39f826a835d6060bc3b43dae7 Mon Sep 17 00:00:00 2001 From: Sander Vanheule Date: Wed, 9 Jun 2021 15:10:03 +0200 Subject: [PATCH] regmap: mdio: Fix regmap_bus pointer constness MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A const qualifier was omitted in the declaration of the regmap_bus pointer, resulting in the following errors: drivers/base/regmap/regmap-mdio.c: In function ‘__regmap_init_mdio’: drivers/base/regmap/regmap-mdio.c:87:7: warning: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers] 87 | bus = ®map_mdio_c22_bus; | ^ drivers/base/regmap/regmap-mdio.c:89:7: warning: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers] 89 | bus = ®map_mdio_c45_bus; | ^ Fix this by ensuring the pointer has the same qualifiers as the assigned values.
