💅 rsi_band_check — kernel API manual, bestie edition

Okay so welcome to rsi_band_check(9), a page from the Kernel API Manual, and no I will not calm down about it. This is the function that programs the band. That's the whole vibe. Band gets programmed. Slay.

✨ NAME ✨

rsi_band_check — this function programs the band 🎀

🦋 SYNOPSIS 🦋

int rsi_band_check (struct rsi_common *common , struct ieee80211_channel
*curchan );

Like, read it slow, it's literally just two pointers and an int coming back at you. Iconic signature. No notes.

🌸 ARGUMENTS 🌸

• common — pointer to the driver private structure. That's where all the driver's personal business lives, iykyk 💖
• curchan — pointer to the current channel structure. Yes, the channel you're on right now, main character energy only 💅

💜 RETURN 💜

• 0 on success 🎉
• the corresponding error code on failure 😭 (it will tell you what went wrong, fr fr)
