Some patches were part of other linux-mainline kernel versions but are not anymore part of the current 4.19.76. Move 0001-Enable-uart3-for-NanoPi-Neo-Air-used-by-BT.patch in linux-mainline_4.19.76.bbappend to avoid error patching file arch/arm/boot/dts/sun8i-h3-nanopi-neo-air.dts Hunk #2 FAILED at 162. 1 out of 2 hunks FAILED -- rejects in file arch/arm/boot/dts/sun8i-h3-nanopi-neo-air.dts Place all patches from Armbian in a separate directory and do all the Balena specific operations in linux-mainline_%.bbappend only.

Subject: [PATCH 139/146] Bluetooth: Add new quirk for broken local ext
|
|
features max_page
|
|
|
|
Some adapters (e.g. RTL8723CS) advertise that they have more than
|
|
2 pages for local ext features, but they don't support any features
|
|
declared in these pages. RTL8723CS reports max_page = 2 and declares
|
|
support for sync train and secure connection, but it responds with
|
|
either garbage or with error in status on corresponding commands.
