net/mlx5: Fix build break when CONFIG_SMP=n
[ Upstream commit e3ca34880652250f524022ad89e516f8ba9a805b ] Avoid using the kernel's irq_descriptor and return IRQ vector affinity directly from the driver. This fixes the following build break when CONFIG_SMP=n include/linux/mlx5/driver.h: In function ‘mlx5_get_vector_affinity_hint’: include/linux/mlx5/driver.h:1299:13: error: ‘struct irq_desc’ has no member named ‘affinity_hint’ Fixes: 6082d9c9c94a ("net/mlx5: Fix mlx5_get_vector_affinity function") Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> CC: Randy Dunlap <rdunlap@infradead.org> CC: Guenter Roeck <linux@roeck-us.net> CC: Thomas Gleixner <tglx@linutronix.de> Tested-by: Israel Rukshin <israelr@mellanox.com> Reported-by: kbuild test robot <lkp@intel.com> Reported-by: Randy Dunlap <rdunlap@infradead.org> Tested-by: Randy Dunlap <rdunlap@infradead.org> Acked-by: Thomas Gleixner <tglx@linutronix.de> Tested-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: David S.
