Kernel build fails on kernel 6.6.20+rpt-rpi-v7 (armv7l) (bookworm)

I fixed this by running ./uninstall.sh in the driver directory, installing the 6.6 kernel, then re-running ./install.sh. This may help for you.

Doesn't work for me , you can install the latest kernel but it will fail again when you try build the wm8960 kernel module in 6.6.20. The definition of "snd_soc_of_get_dai_name" has changed in soc.h compared to 6.1 kernel.

6.1: int snd_soc_of_get_dai_name(struct device_node *of_node, const char **dai_name);

6.6:

int snd_soc_of_get_dai_name(struct device_node *of_node, const char **dai_name, int index);

I made a quick and dirty fix so that the module could be compiled under 6.6.20+rpt-rpi-v7 Audio works but I'm not a programmer.

I can confirm this appears to work, although I am dubious about removing a parameter from a function. (The patch did not work for me, and I had to edit the code manually based on the patch.)
