| Subject: nvme-pci: Use single IRQ vector for old Apple models |
| |
| From: Andy Shevchenko <andriy.shevchenko@linux.intel.com> |
| |
| [ Upstream commit 98f7b86a0becc1154b1a6df6e75c9695dfd87e0d ] |
| |
| People reported that old Apple machines are not working properly |
| if the non-first IRQ vector is in use. |
| |
| Set quirk for that models to limit IRQ to use first vector only. |
| |
| Based on original patch by GitHub user npx001. |
