[PATCH 2/8] staging: sm750fb: remove unused CSC register definitions
From: Gabriel Windlin
Date: Tue Mar 03 2026 - 18:26:20 EST
The Color Space Conversion (CSC) register macros defined in ddk750_reg.h
are not referenced anywhere in the driver. Remove them to reduce dead
code as noted in the TODO file.
