Subject: [PATCH v2 0/4] fpga: fpga-mgr: move compat_id from fpga_mgr to dfl

From: Tom Rix <trix@...hat.com>

A followup to
https://lore.kernel.org/linux-fpga/aa06a7ca-eff3-5c0d-f3b0-f1d9ddb74526@redhat.com/
The current storing of compat_id in fpga_manager is dfl specific.
This makes the refactoring of the release()'s complicated because there
is a dfl specific flavor of register().

Keeping the compat_id sysfs abi, each implementation through the new
compat_id_show() fpga_region op can print out whatever value they need
to the sysfs.  Currently only dfl does.

Since there are now two ops for fpga_region, give fpga_region its
own ops table.  Add a wrapper for get_bridges().

Changes from
v1
  Completely written to keep sysfs abi

Tom Rix (4):
  fpga: region: introduce fpga_region_ops
  fpga: region: introduce compat_id_show op
  fpga: dfl: implement the compat_id_show region op
  fpga: remove compat_id from fpga_manager and fpga_region
