From 33e7ca5a9b6a0dc1c894c14fd8e29b816f9a6f55 Mon Sep 17 00:00:00 2001 From: Sam Protsenko Date: Tue, 7 Nov 2023 14:13:49 -0600 Subject: [PATCH] serial: s5p: Use dev_read_addr_ptr() to get base address As the address read from device tree is being cast to a pointer, it's better to use dev_read_addr_ptr() API for getting that address. The more detailed explanation can be found in commit a12a73b66476 ("drivers: use dev_read_addr_ptr when cast to pointer").
