[PATCH v6 0/3] staging: octeon: replace pr_* with dev_* logging

[Ayush Mukkanwar]

This patch series replaces pr_warn(), pr_err(), and pr_info() calls
with device-aware logging functions (dev_warn(), dev_err(),
netdev_err(), and netdev_info()) throughout the Octeon ethernet driver.
To support this, struct platform_device is passed through the memory
allocation and receive call chains. Additionally, the receive group
state (oct_rx_group) and the rx refill delayed work (rx_refill_work)
are refactored from static globals into the per-device platform data
structure (octeon_ethernet_platform).
Changes in v6:
- Squash the structural refactoring into the same patch that
  introduces the platform data, so each patch is a self-contained
  logical change with no inconsistent intermediate states (Greg)
- Rename local platform device data variables from `plt` to `plat`
  to adhere to standard kernel naming conventions (Dan Carpenter)
Changes in v5:
- Pass struct platform_device instead of struct device through
  ethernet-mem and ethernet-rx call chains (Greg)
- Move static oct_rx_group[16] array into the platform device
  private structure to eliminate file-scoped global state (Greg)
- Update kdoc parameter names to match renamed parameters
Changes in v4:
- Broke the series into much smaller, focused patches to ease review
- Removed the global cvm_oct_rx_refill_work by introducing a per-device
  struct octeon_ethernet_platform, allocated during probe
- Retrieved the device pointer via platform_get_drvdata() and passed it
  down the call chain (NAPI poll -> rx refill -> mem free/fill) as the
  first argument to avoid global state
- Note: Dropped the ethernet-spi.c IRQ handler conversions from this
  series for now, as those errors are SPI4 bus-level
Changes in v3:
- Use netdev_err() instead of dev_err() in ethernet-spi.c
- Pass the netdev pointer directly to request_irq/free_irq
  instead of dev->dev.parent
- Move the device pointer to be the first argument in helper
  functions
- Fix checkpatch alignment and line-length warnings
- Add missing @dev kernel-doc parameter descriptions
- Wrap commit message body to 75 characters
- Fix author name formatting
Changes in v2:
- Instead of adding pr_fmt() macros, replace pr_*() calls with
  proper dev_*() and netdev_*() calls
- Thread device pointer through call chains via function parameters
- Introduce struct octeon_ethernet_platform to pass device pointer
  through work queue callbacks via container_of
- Store device pointer in oct_rx_group for NAPI poll functions
- Use dev_id in interrupt handler to pass and retrieve device pointer
