From mboxrd@z Thu Jan 1 00:00:00 1970 From: arnd@arndb.de (Arnd Bergmann) Date: Tue, 19 May 2015 14:49:44 +0200 Subject: [PATCH] ARM: shmobile: only select sound drivers that build Message-ID: <5616798.tmraH8vpuI@wuerfel> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org A couple of codec drivers are selected by shmobile platform code, but depend on I2C, which results in a build error: sound/soc/codecs/ak4642.c:638:1: warning: data definition has no type or storage class module_i2c_driver(ak4642_i2c_driver); ^ sound/soc/codecs/ak4642.c:638:1: error: type defaults to 'int' in declaration of 'module_i2c_driver' [-Werror=implicit-int] sound/soc/codecs/ak4642.c:638:1: warning: parameter names (without types) in function declaration sound/soc/codecs/ak4642.c:627:26: warning: 'ak4642_i2c_driver' defined but not used [-Wunused-variable] This ensures that we do not enable the respective drivers when I2C is disabled.
