    ASoC: sigmadsp: Split regmap and I2C support into separate modules · 6b10998d
    Lars-Peter Clausen authored
    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.
