Upgrade Redpine WLAN/BT driver to ver. 1.2 (production release)

[Shrirang Bagul]

Upgrade the Redpine WLAN/BT RS9113 driver in Ubuntu Xenial kernel to ver. 1.2. This version is supposed to be a production release.

This is the latest version of the driver provided by Redpine. For now, this driver is enabled only on x86, x86_64 architectures. The impact is restricted to { SDIO_DEVICE(0x041B, 0x9330) } for SDIO based WiFi-BT modules and on USB bus, this driver binds only to RS9113, lets upstream kernel driver handle other RSI chipsets.

Fixes since previous release(see lp: #1694607)

Other fixes:
- Redpine vendor driver - Switching to AP mode causes kernel panic (lp: #1700941)
- ubuntu/rsi driver has several issues as picked up by static analysis (lp: #1694733)

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1697829

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Kleber Sacilotto de Souza (kleber-souza)]

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-xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed-xenial'.

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.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Hi @Shrirang,

Could you please verify if the updated driver on the Xenial kernel currently on -proposed works as expected?

Thanks,
Kleber

[Shrirang Bagul (shrirang-bagul)]

Hi @Kleber,

This driver was verified on a test kernel snap based on Ubuntu Xenial 4.4.0-85.108
(published here: http://kernel.ubuntu.com/git/snb/ubuntu-xenial.git/log/?h=caracalla-lp-for-kt)

The kernel snap for QA testing will be built from the kernel in -updates.

Thanks,
Shrirang

[Kleber Sacilotto de Souza (kleber-souza)]

Tagging bug with verification-done-xenial since the driver has been tested on a Xenial-based snap.

Thanks, @Shrirang.
