* Recycling of megous v5.16.4 patches The patches were sorted as far as possible. Some patches are renamed according to their place of application. The length of the patch name has been changed to improve readability using the `git format-patch --filename-max-length=75` method. The folder containing the patches will have the name `patches.name` and the corresponding file `series.name` for the convenience of processing and moving them upstream. But the control file remains `series.conf`.

Subject: [PATCH 092/446] 8723cs: Disable use of NAPI
|
|
|
|
It's useless anyway, since the driver doesn't disable interrupts,
|
|
and doesn't poll the HW directly either, but keeps RX interrupt
|
|
enabled and polls the queue that's filled from a HW interrupt.
|
|
|
|
Driver's NAPI implementation is borked anyway, and prevents
|
|
the NOHZ tick-stop for no reason:
