[logic88]

When I execute this command：
pi@raspberrypi:~ $ sudo modprobe snd-i2s_rpi rpi_platform_generation=0
Just report an error：modprobe：FATAL: Module snd-i2s_rpi not found in directory /lib/modules/5.15.61-v8+

But it does have this under the folder：
drwxr-xr-x 3 root root 4096 Sep 22 10:51 5.15.61-v8+
drwxr-xr-x 3 root root 4096 Jan 13 21:43 5.15.84-v8+
