[PATCH 1/4] macfb: don't clear interrupts when writing to DAFB_RESET


From: Mark Cave-Ayland
Subject: [PATCH 1/4] macfb: don't clear interrupts when writing to DAFB_RESET
Date: Thu, 26 Oct 2023 09:56:47 +0100

Traces from A/UX suggest that this register is only used to reset the 
framebuffer
LUT (colour lookup table) and not any other device state.
