🎀 zynqmp_disp_avbuf_set_format — the Kernel API Manual, bestie edition 🎀

okay so real talk, this is a page from the Kernel API Manual (yes, that Kernel API Manual) and it's all about one very specific little function. it's not the flashiest function at the party but she does her job and she does it well 💅

                                   struct zynqmp_disp_layer *layer ,
                                   const struct zynqmp_disp_format *fmt );

like, void return, three args, no drama. she's lowkey iconic for keeping it simple 🫶
