From 6c72a5bc4df4565164569d4833efc6f19c44dcbc Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 15 Sep 2021 20:30:21 +0200 Subject: [PATCH] lib/logic_iomem: Fix 32-bit build [ Upstream commit 4e84139e14af5ea60772cc4f33d7059aec76e0eb ] On a 32-bit build, the (unsigned long long) casts throw warnings (or errors) due to being to a different integer size. Cast to uintptr_t first (with the __force for sparse) and then further to get the consistent print on 32 and 64-bit.
