From de98a43eb76b8442c02a2fe31c2a50d72cf6ded3 Mon Sep 17 00:00:00 2001 From: Vignesh Raghavendra Date: Sat, 9 Nov 2019 10:36:18 +0530 Subject: mfd: ti_am335x_tscadc: Fix static checker warning It is possible that platform_get_resource() might return NULL and therefore code needs to check for this condition before de-referencing the pointer. Therefore move the de-referencing of 'res' pointer after devm_ioremap_resource() which would have checked the validity of the pointer.
