Subject: [PATCH] linux-4.14.13: Build out of tree aacraid module

Thomas reports the problem below [1].

> further testing of the stock aacraid-driver yielded some deficits in
> the sys-fs representation. Aparently it doesn't link the disk devices
> to enclosure slots, a thing that the off-tree microsemi driver does
> (and the LSI driver also, so i deem it's 'good-practice' in modern HBA
> drivers). Indeed it doesn't affect the functionality, but it hampers
> maintenance and client-tools a bit more than just a bit.

> Here is the location info of the missing sys-fs parts
> short way, where as the `device` part is missing:
> ```
> #ls -la /sys/class/enclosure/7:0:80:0/Disk001
> drwxr-xr-x  3 root system    0 Jan 10 13:08 .
> drwxr-xr-x 19 root system    0 Jan 10 13:07 ..
> -rw-r--r--  1 root system 4096 Jan 11 12:56 active
> lrwxrwxrwx  1 root system    0 Jan 10 13:08 device ->
> ../../../../../../../port-7:1/end_device-7:1/target7:0:65/7:0:65:0

> -rw-r--r--  1 root system 4096 Jan 11 12:56 uevent
> ```
> The true location would be:
> ```
> /sys/devices/pci0000:00/0000:00:03.0/0000:04:00.0/host7/port-7:16/end_device-7:16/target7:0:80/7:0:80:0/enclosure/7:0:80:0/Disk001
