From 4e3b9a6eae987c80330e5253754dab35acc2a63b Mon Sep 17 00:00:00 2001 From: Anshuman Khandual Date: Mon, 10 Jul 2023 11:54:56 +0530 Subject: [PATCH] coresight: etm4x: Drop iomem 'base' argument from etm4_probe() 'struct etm4_drvdata' itself can carry the base address before etm4_probe() gets called. Just drop that redundant argument from etm4_probe().
