xilinx_dma_...an_resources(9)

💖 NAME 💖

This is the xilinx_dma_...an_resources(9) page from the Kernel API Manual, bestie.

xilinx_dma_alloc_chan_resources — Allocate channel resources. That's the whole vibe: it's the function that allocates channel resources. ✨

🎀 SYNOPSIS 🎀

int xilinx_dma_alloc_chan_resources (struct dma_chan *dchan );

🌸 ARGUMENTS 🌸

• dchan — DMA channel. Yep, that's the one argument: the DMA channel.

💫 RETURN 💫

Okay so the RETURN section is literally empty in this page — no documented return values, no error list, no extra notes. The synopsis does show the function as returning int, and that's all the page gives us. No cap. 🫶
