I want my phone kernel to support the CH341 driver, so I made changes in the configuration as CONFIG_USB_SERIAL=y and CONFIG_USB_SERIAL_CH341=y. Then I followed this guide
to compile the kernel, but I'm getting the following issue:

So how to fix this error?
I tried the 4.8 and 4.9 compilers, but that didn't work.
