msi_free_msi_descs_range(9)

✨ NAME ✨

msi_free_msi_descs_range — Free a range of MSI descriptors of a device in the default irqdomain

Okay so literally what it says on the tin, bestie. This function is all about freeing a range of MSI descriptors for a device in the default irqdomain. It's giving cleanup era. 💅

🌸 SYNOPSIS 🌸

void msi_free_msi_descs_range (struct device *dev , unsigned int first , unsigned int last );

🎀 ARGUMENTS 🎀

• dev — Device for which to free the descriptors. Like, the device whose descriptors you're freeing. No cap, it's that simple. 🫶
• first — Index to start freeing from (inclusive). So you're starting right here, and yes, this index is included. Fr fr. ✨
• last — Last index to be freed (inclusive). This is the final index you're freeing, and it's included too. Slay. 💖

Bestie, this is kernel API, so handle with care. But you got this! 💪
