This patch series addresses maintainer feedback and fixes build errors
in the atomisp driver.

Patch 1: Standardizes the 'Bridge' structs significantly by using
v4l2_rect instead of custom shadow structs and aligning ia_css_region
members with V4L2 conventions.
Patch 2: Introduces a helper function for statistics buffer allocation
to reduce code duplication and centralize error handling logic.
Patch 3: Adds missing error propagation for IRQ enable and XNR
configuration to improve robustness.

Changes in v4:
- Drop overflow fix (long long casts) from Patch 1 to keep it a clean
  refactor/rename patch (Dan Carpenter).
- Fix extra new lines in commit messages (Dan Carpenter).
- Strictly wrap commit messages to 72 characters (Dan Carpenter).

Changes in v3:
- Remove unnecessary s32/u32 casts in atomisp_cmd.c (Dan Carpenter).
- Propagate error codes in atomisp_ioctl.c (Dan Carpenter).
- Update commit message for Patch 3 (Dan Carpenter).
- Wrap cover letter and commit messages to 75 characters (Dan Carpenter).
- Sent as a new thread.

Changes in v2:
- Split into a 3-patch series.
- Standardized internal CSS types.
- Fixed integer overflow safety.

This series is based on the latest staging/next tree and has been
verified with checkpatch.pl --strict.
