Bug Description

[SRU Justification]

[Impact]
Micphone-mute LED indicator on Dell Latitude 3310 keyboard may always
shown as on or off.

[Fix]
* fe486138788ba4 [1]: dell-laptop: Add 2-in-1 devices to the DMI whitelist
* c8ba9db2a790c0 [2]: dell-laptop: Removed duplicates in DMI whitelist

[Test Case]
Verified on Dell Latitude 3310.

[Regression Risk]
Low. The two target patch was landed to v4.16 and is already in
production use for a long time. Besides, this changeset only addes new
IDs (and remove duplicated ones), so it doesn't affect existing systems
but fix those affected ones.

========= Original Description =========

This device has unsupported DMI Chassis Type:

  $ sudo dmidecode | grep -A2 -B1 ^Chassis
  Handle 0x0003, DMI type 3, 22 bytes
  Chassis Information
          Manufacturer: Dell Inc.
          Type: Convertible

So we need to SRU:
* fe486138788ba4 [1]: dell-laptop: Add 2-in-1 devices to the DMI whitelist
* c8ba9db2a790c0 [2]: dell-laptop: Removed duplicates in DMI whitelist

This should only affect 4.15 kernel as they have been landed to v4.16.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
