Bug Description

[Impact]

 Wifi doesn't work on systems with Centrino Advanced-N 6235 [8086:526a].

[Fix]

 The patch adds the device ID 0x526A.

[Test Case]

 Wifi works after installing test kernel (#19 & #20 in LP:1920180)

[Regression Potential]

 Low to none. This adds a hardware ID and does not affects systems
 output such a wifi card.

[Note]

 Patch was also sent for upstream reviews and can be viewed at
 https://www.spinics.net/lists/stable/msg452937.html

It will take a while for a patch to be merged, so you will lose wifi 6235 if you update to newer kernels.

There are processes to merge a patch. A normal process is like below:

1. a patch is sent to upstream (cc to stable kernel)
2. it gets reviewed and merged by a maintainer, and is included in next kernel release
3. it gets merged to stable kernels (in this case, 5.4 kernel)
4. a kernel is released by a distro (i.e. in this case Ubuntu kernel)

Note: I don't know how Linux Mint picks up Ubuntu kernel and there may be some time too.
