[v2,0/8] fpga: Populate dev_release functions

Message

Russ Weight June 9, 2021, 10:11 p.m. UTC

The FPGA framework has a convention of using managed resource functions
to allow parent drivers to manage the data structures allocated by the
class drivers. They use an empty *_dev_release() function to satisfy the
class driver.

This is inconsistent with linux driver model.

This is a complete re-do of the previous patch set entitled
"fpga: Use standard class dev_release function". These changes populate the
class dev_release callback functions while maintaining the current API.
Additional changes are made to maintain consistency with the driver model.

For more context on these changes, refer to this email thread:

Changelog v1 -> v2:
  - Moved the renaming of "dev" to "parent" into a separate patch each for
    fpga-mgr, fpga-bridge, fpga-region.
  - Restored the call to fpga_mgr_free() in devm_*_mgr_release() instead of 
    changing it to put_device().
  - Replaced patch "fpga: altera-pr-ip: Remove function alt_pr_unregister"
    with "fpga: altera-pr-ip: Remove function alt_pr_unregister". This patch
    removes the alt_pr_unregister() function altogether, instead of just
    removing portions of it.

Russ Weight (8):
  fpga: altera-pr-ip: Remove function alt_pr_unregister
  fpga: stratix10-soc: Add missing fpga_mgr_free() call
  fpga: mgr: Rename dev to parent for parent device

  fpga: region: Rename dev to parent for parent device
  fpga: mgr: Use standard dev_release for class driver
  fpga: bridge: Use standard dev_release for class driver
  fpga: region: Use standard dev_release for class driver
