主线4.19 增加声卡驱动，启动失败了？

参考: https://whycan.cn/t_2041.html#p39583

针对主线kernel4.19，我增加了声卡驱动，原来正常的启动的固件uboot和rootfs没有修改，编译后zImage和dtb打包烧写后启动失败，求指点，这大致是什么原因？

编译过程中的错误，需要修改源码如下：

1.linux_patch\drivers\dma\Makefile屏蔽mediatek和ti

#obj-y += mediatek/

obj-y += qcom/

#obj-y += ti/

obj-y += xilinx/

2.linux_patch\drivers\dma\Kconfig屏蔽mediatek和ti

source "drivers/dma/bestcomm/Kconfig"

#source "drivers/dma/mediatek/Kconfig"

source "drivers/dma/qcom/Kconfig"

source "drivers/dma/dw/Kconfig"

source "drivers/dma/hsu/Kconfig"

source "drivers/dma/sh/Kconfig"

#source "drivers/dma/ti/Kconfig"

3. linux_patch\sound\soc\sunxi\suniv-codec.c结构成员use_pmdown_time修改为pmdown_time

.pmdown_time = 1, /*.use_pmdown_time = 1,*/

经过以上几处修改，可以正常开机，可以正常识别声卡。
