✨ SYNOPSIS ✨

int w1_therm_add_slave (struct w1_slave *sl );

πŸ¦‹ DESCRIPTION πŸ¦‹

Bestie, picture this: the master discovers a new slave on the bus, and this function gets called. Its whole job is to initialize the slave's state before any communication even starts. No cap, that's it β€” but it's important πŸ’–


πŸ”₯ RETURN πŸ”₯

Returns 0 if it's a success, and a negative kernel code otherwise. So 0 is the good ending, negative is the "oop" ending πŸ’€
