[PATCH 1/2] HID: corsair: fix DMA buffers on stack

2017-01-12 Thread Johan Hovold
Not all platforms support DMA to the stack, and specifically since v4.9 this is no longer supported on x86 with VMAP_STACK either. Note that the macro-mode buffer was larger than necessary. Fixes: 6f78193ee9ea ("HID: corsair: Add Corsair Vengeance K90 driver") Cc: stable
