From 0c3457926e7e65710f32e02920c7d423417c93a2 Mon Sep 17 00:00:00 2001 From: Robin Murphy Date: Fri, 19 Apr 2024 17:54:40 +0100 Subject: OF: Retire dma-ranges mask workaround The fixup adding 1 to the dma-ranges size may have been for the benefit of some early AMD Seattle DTs, or may have merely been a just-in-case, but either way anyone who might have deserved to get the message has hopefully seen the warning in the 9 years we've had it there. The modern dma_range_map mechanism should happily handle odd-sized ranges with no ill effect, so there's little need to care anyway now. Clean it up.
