okay bestie, welcome to the Kernel API Manual — today’s little icon is all about __ssp_disable_rxwm, and yes, it does exactly what the name says. 💅

✨ SYNOPSIS

void __ssp_disable_rxwm (struct sifive_serial_port *ssp );

🎀 ARGUMENTS

• ssp — a pointer to a struct sifive_serial_port, fr fr. That’s the whole argument.
