Subject: [PATCH 0/5] drm/solomon: Code improvements and DRM helper adoption

This patch series improves the Solomon SSD130x DRM driver by adopting
existing DRM helpers, improving code clarity, and following kernel
coding standards.

* Patch #1 moves DRM GEM framebuffer CPU access calls to make critical
  sections more visible and maintainable.
* Patch #2 replaces WARN_ON with drm_WARN_ON_ONCE to prevent log spam.
* Patch #3 adopts drm_crtc_helper_mode_valid_fixed() for mode
  validation.
* Patch #4 adopts drm_connector_helper_get_modes_fixed() for mode
  management.
* Patch #5 enforces one assignment per line per kernel coding style.

These improvements reduce code duplication by leveraging existing DRM
infrastructure and enhance code readability without changing
functionality.
