π hl_release_firmware(9) π
okay so bestie, welcome to the Kernel API Manual β¨ β yes we're doing kernel docs today and yes it's gonna slay. This one's hl_release_firmware, and honestly? It's giving "small but mighty" π
πΈ NAME πΈ
hl_release_firmware β release FW π¦
like, you know that firmware you grabbed earlier? yeah. this is the part where you let it go. release. periodt. π
β¨ SYNOPSIS β¨
void hl_release_firmware (const struct firmware *fw );
one line. one function. zero drama (mostly) π«Ά
π ARGUMENTS π
fwβ the fw descriptor π this is the little handle to the firmware thing, and it's what you're handing back. that's it. that's the whole argument list, bestie.
β NOTE β
okay so this is the important bit π β this here <hotpink>inline function</hotpink> was added specifically to serve as a comprehensive mirror for the hl_request_fw function. so like, hl_request_fw gets you the firmware, and this one is its mirror-image counterpart. comprehensive mirror energy πͺβ¨ iykyk.
no cap, it's an inline function β that's literally what the note says, not me being extra π
π¦ SEE ALSO π¦
okay this list is long and i am obsessed π so buckle up, we're going through the whole friend group π
