From ce9ff57d393db86a34ba3f817d7fb886b7c278dc Mon Sep 17 00:00:00 2001 From: Petr Tesarik Date: Wed, 2 Aug 2023 18:33:21 +0200 Subject: [PATCH] parisc: pci-dma: remove unused and dead EISA code and comment Clearly, this code isn't needed, but it gives a false positive when grepping the complete source tree for coherent_dma_mask.
