[PATCH v4 0/5] staging: media: atomisp: cleanup pci/hmm/ code
From: Nikolay Kulikov
Date: Fri Aug 14 2026 - 11:11:32 EST
This series removes unused functions and replaces obscure
variable-checking macros with clear conditional statements.
Changes in v4:
- In commit 1, include the removal of the static 'hmm_bo_vm_ops'
structure and the hmm_bo_vm_open() and hmm_bo_vm_close()
functions (whose addresses are stored in that structure), as
they have also become unused and are triggering compiler
warinigs (I removed Andy Shevchenko's Rb tag because of this
change).
- Add the Rb tag (commit 3).
- Add the base commit hash.
- Add links to v1/v2/v3.
Changes in v3:
- Split the last patch into two (inlining macros and removing
the file).
- Replace variable initialization with assignment, followed
immediately by a check.
Changes in v2:
- Squashed the function removals in pci/hmm/hmm.c and
pci/hmm/hmm_bo.c into a single commit.
- Add commits to cleanup macros from include/hmm/hmm_common.h,
as suggested by Andy Shevchenko.
