Enable support for Texas Instruments TAS2781 Smart AmplifierDigital input mono Class-D and DSP-inside audio power amplifiers.Note the TAS2781 driver implements a flexible and configurablealgo coff setting, for one, two, even multiple TAS2781 chips.
You changed coff->coefficient below as suggested by Pierre-Louis Bossart but you forgot to change it here, and this will surely perplex people when configuring the kernel.
