From d710c7e84187088cb157ab4131ca50a1236a931a Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Sun, 12 Sep 2021 11:15:10 +0800 Subject: [PATCH] gpio: sifive: Fix -Wint-to-pointer-cast warning dev_read_addr() returns a value of type fdt_addr_t which is a 64-bit address and plat->base is a pointer. In a 32-bit build, this causes the following warning seen when building sifive-gpio.c: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] Change to use dev_read_addr_ptr().
