[PATCH v3 0/3] Additional miscdevice fops parameters

[Alice Ryhl <aliceryhl@google.com>]

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@google.com

Changes in v2:
- Access the `struct miscdevice` from fops->open().
- Link to v1: https://lore.kernel.org/r/20241203-miscdevice-file-param-v1-1-1d6622978480@google.com
