Merge branch 'mlx5-new-device-events'
Saeed Mahameed says:
====================
Mellanox, mlx5 new device events
The following series is for mlx5-next tree [1], it adds the support of two
new device events, from Ilan Tayari:
1. High temperature warnings.
2. FPGA QP error event.
In case of no objection this series will be applied to mlx5-next tree
and will be sent later as a pull request to both rdma and net trees.
[1] https://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux.git/log/?h=mlx5-next
v1->v2:
- improve commit message of the FPGA QP error event patch.
====================
