From 18311a766c587fc69b1806f1d5943305903b7e6e Mon Sep 17 00:00:00 2001 From: Raag Jadav Date: Wed, 12 Feb 2025 11:55:02 +0530 Subject: [PATCH] err.h: move IOMEM_ERR_PTR() to err.h Since IOMEM_ERR_PTR() macro deals with an error pointer, a better place for it is err.h. This helps avoid dependency on io.h for the users that don't need it.
