kernel/linux.git/Documentation/driver-api/virtio, branch v6.19.11Linux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=v6.19.112024-04-08T08:11:04+00:00virtio: store owner from modules with register_virtio_driver()2024-04-08T08:11:04+00:00Krzysztof Kozlowskikrzysztof.kozlowski@linaro.org2024-03-31T08:43:48+00:00urn:sha1:ffe6176b7f53ca0c99355f13e14a33a40cf49406
Modules registering driver with register_virtio_driver() might forget to
set .owner field. i2c-virtio.c for example has it missing. The field
is used by some other kernel parts for reference counting
(try_module_get()), so it is expected that drivers will set it.
Solve the problem by moving this task away from the drivers to the core
virtio code, just like we did for platform_driver in
commit 9447057eaff8 ("platform_device: use a macro instead of
platform_driver_register").
Fixes: 3cfc88380413 ("i2c: virtio: add a virtio i2c frontend driver")

A sentence that checks for later spec version is meant for developers
hacking the documentation source. Make it comment block (hidden from
actual output).

"It's at this stage that" means "At this point", so use the latter as it
is more effective.

them from remaining texts.
While at it, describe the second target.
