[PATCH 7/8] staging: sm750fb: remove unused CURRENT_GATE, CRT_HWC, and DMA register definitions
From: Gabriel Windlin
Date: Tue Mar 03 2026 - 18:28:12 EST
The CURRENT_GATE_VGA, CURRENT_GATE_PWM, CURRENT_GATE_SSP, and
CURRENT_GATE_ZVPORT bit field macros, the CRT_HWC hardware cursor
register macros, the DMA_1_SOURCE, DMA_1_DESTINATION, and
DMA_1_SIZE_CONTROL register macros, and the unused
DMA_ABORT_INTERRUPT_ABORT_0, DMA_ABORT_INTERRUPT_INT_1, and
DMA_ABORT_INTERRUPT_INT_0 bit field 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.
