While Linux 5.12-rc2 released on Friday due to that prominent corruption bug, there still is some Sunday kernel fun with Greg Kroah-Hartman releasing a slew of stable kernel updates including Linux 5.11.4 and 5.10.21 LTS.

While I normally don't write about every kernel point release, I do when there are some prominent changes worth highlighting. With Linux 5.11.4 there are some notable back-ports from 5.12 and other work worth mentioning, including:

- New Intel WiFi PCI IDs being added to the IWLWIFI driver for the So and Qu families. These new PCI IDs for several Intel WiFi AX201/AX203 variants are already being used by some OEMs and originally this patch was trying to get in ahead of Linux 5.11 being declared while now after going in through Linux 5.12 has worked its way in as a backport.

- A REBAR size quirk for the Sapphire Radeon RX 5600 XT PULSE for AMD Smart Access Memory (Resizable BAR) as it only advertised 256MB/512MB/1GB but it also supports 2GB/4GB/8GB so a rebar size quirk is now added to fully access the BAR0.

- Backporting from Linux 5.12 the Pioneer DJM-750 DJ mixer support. The Pioneer DJM-450 was also added as a quirk.

- A number of Intel ASoC sound quirks added for various tablets.

- A sound support quirk for the Intel NUC 10 was added to the Realtek HDA code.

- Various minor bug fixes.

See more in Linux 5.11.4 and 5.10.21 for the older long-term support kernel.

Also out today is Linux 5.4.103, 4.19.179, 4.14.224, 4.9.260, and 4.4.260 for a busy Sunday of kernel updates.
