💅 reset_control_bulk_get_optional_exclusive — like, the chill version of the exclusive bulk getter

okay so bestie, this is a page from the Kernel API Manual (the 9 section, kernel internals, iykyk) and it's about reset_control_bulk_get_optional_exclusive. Which, yes, is a whole mouthful — she's giving "the optional variant of reset_control_bulk_get_exclusive()" and honestly she ate. Let's get into it 🎀

✨ NAME ✨

reset_control_bulk_get_optional_exclusive — lowkey just reset_control_bulk_get_exclusive() but make it optional 🦋

🌸 SYNOPSIS 🌸

int reset_control_bulk_get_optional_exclusive (struct device *dev , int
num_rstcs , struct reset_control_bulk_data *rstcs );

that's the whole signature, no cap. three args, one int coming back at you 💫

🎀 ARGUMENTS 🎀

  • dev — the device that's gonna get reset by the controller. main character energy, fr.
  • num_rstcs — how many entries are chillin' in the rstcs array. like, the headcount.
  • rstcs — an array of struct reset_control_bulk_data, with the reset line names already set. not me making sure those names are set before calling 👀

💜 DESCRIPTION 💜

okay so here's the vibe: this is the optional variant of reset_control_bulk_get_exclusive. what does "optional" mean in this context? it means if any of the requested resets aren't specified in the device tree, this function doesn't throw a whole tantrum and return an error — instead it just sets them to NULL. graceful. iconic. 💅

like, no error, just NULL. she simply moves on. periodt.
