charset=UTF-8 Content-Transfer-Encoding: 8bit This series replaces the set_DAC macro with a local static function, corrects the DAC power-off bit handling, and removes an empty software I2C acknowledgement helper and its ineffective parameter. The first and third patches preserve existing behavior. The second patch maps the extracted 0/1 DAC state to bit 20 rather than OR-ing it into bit 0 of MISC_CTRL. Based on staging-next at 6628e7d4c6b (Linux 7.4-rc1). Validation: - All SM750 driver objects compiled and linked into sm750fb.o with W=1, CONFIG_FB=y, CONFIG_STAGING=y, and CONFIG_FB_SM750=m. - A standalone mocked-register test checked 72 DAC state and register preservation cases: 36 failed before the fix and none failed afterward. - checkpatch.pl reported no errors or warnings. - git diff --check passed. Hardware testing was not performed.
