[PATCH v3 0/3] Additional miscdevice fops parameters

From: Alice Ryhl
Date: Tue Dec 10 2024 - 04:43:19 EST


This could not land with the base miscdevice abstractions due to the
dependency on File.

The last two patches enable you to use the `dev_*` macros to print
messages in miscdevice drivers.

Changes in v3:
- Fix build error in fops->open() patch.
- Improve wording of some comments in fops->open() patch.
- Update commit message with more info on why `struct miscdevice` is
only made available in fops->open() and not other hooks.
- Include Lee's device accessor patch, since it's a needed component to
use the `dev_*` printing macros with miscdevice.
- Link to v2: https://lore.kernel.org/r/20241209-miscdevice-file-param-v2-0-83ece27e9ff6@xxxxxxxxxx

Changes in v2:
