[PATCH 5/8] staging: sm750fb: remove unused memory arbitration register definitions
From: Gabriel Windlin
Date: Tue Mar 03 2026 - 18:26:23 EST
The LOCALMEM_ARBITRATION and PCIMEM_ARBITRATION 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.
