Gwendal Grignou 19c82681db HID: intel-ish-hid: Use dma_alloc_coherent for firmware update ... commit f97ec5d75e upstream. Allocating memory with kmalloc and GPF_DMA32 is not allowed, the allocator will ignore the attribute. Instead, use dma_alloc_coherent() API as we allocate a small amount of memory to transfer firmware fragment to the ISH. On Arcada chromebook, after the patch the warning: "Unexpected gfp: 0x4 (GFP_DMA32). Fixing up to gfp: 0xcc0 (GFP_KERNEL). Fix your code!" is gone. The ISH firmware is loaded properly and we can interact with the ISH: > ectool --name cros_ish version ...
