From: Lars-Peter Clausen Date: Fri, 6 Jun 2014 12:09:17 +0000 (+0200) Subject: ASoC: sigmadsp: Split regmap and I2C support into separate modules X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6b10998d74398ec8745d54dfdcbcc1eb445a2f9f;p=openwrt%2Fstaging%2Fblogic.git ASoC: sigmadsp: Split regmap and I2C support into separate modules When the SigmaDSP module is built-in, but the I2C core is build as a module we'll get a undefined reference: sound/built-in.o: In function `sigma_action_write_i2c': :(.text+0x5d8d4): undefined reference to `i2c_master_send' This can happen if a audio driver that is using the regmap SigmaDSP interface is built into the kernel, but core I2C support is build as a module. To fix this split the SigmaDSP module into three modules, one module providing the core infrastructure and two small modules implementing the regmap and I2C interfaces. This allows e.g. the core infrastructure and regmap support to be built into the kernel while I2C support can still be build as a module.
