[PATCH v2 0/2] staging: sm750fb: remove dead VALIDATION_CHIP code

From: Nils Lehnen

Date: Sat Jul 18 2026 - 02:29:25 EST


VALIDATION_CHIP is defined nowhere in the tree, yet fourteen
preprocessor conditionals in the sm750fb DDK files still test it.
Patch 1 resolves all of them (dead branches dropped, always-true
branches kept), as the driver TODO asks under "remove unused code";
patch 2 cleans up the indentation and blank lines the removal leaves
behind.

Verification, both patches: the disassembly of all ten sm750fb object
files (objdump -d, x86, CONFIG_FB_SM750=m) is bit-identical across the
series. Compile-tested only; no SM750 hardware available.

All English text in this series (cover letter, commit messages, code
comments) was translated from a German draft with the assistance of
Claude Fable 5.

v2: resend of v1 -- patch 1/2 of v1 arrived with an empty subject due
to a local send mishap; no code changes.
v1: https://lore.kernel.org/r/20260718055132.441-1-nils.lehnen@xxxxxxxxx
