From 776d875fd4cbb3884860ea7f63c3958f02b0c80e Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Fri, 14 Oct 2022 20:01:17 +0200 Subject: [PATCH] fbdev: stifb: Fall back to cfb_fillrect() on 32-bit HCRX cards When the text console is scrolling text upwards it calls the fillrect() function to empty the new line. The current implementation doesn't seem to work correctly on HCRX cards in 32-bit mode and leave garbage in that line instead. Fix it by falling back to standard cfb_fillrect() in that case.
