Syntax Error in esp32_rmt.c: The compiler choked on line 53 #458
Description
Hello. I was building the firmware for a general esp32 wroom devkit when the build failed and gave this error:

I looked into it and it seems in esp32_rmt.c on line 53 there is a GitHub URL to a pull request (PR #16293 in the main MicroPython repo). It looks like a remnant from a merge commit message, code review comment, or accidental paste during editing. In C, the compiler expects a declaration, statement, or attribute after a token like this, but https://... followed by a colon (:) is treated as invalid syntax (hence the "before ':' token" error).
I think you were trying to fix the driver_ng issue and accidentally copied this here, just edit the line and remove it. ok, bye.
and just incase it is necessary this was the build command i used :
python3 make.py esp32 BOARD=ESP32_GENERIC DISPLAY=ili9486 INDEV=xpt2046.
I am using wsl for windows.
