From 3c12c62ba5fa12c988336a9de5784c6b5fbaac54 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 17 Jul 2020 14:36:46 +0900 Subject: treewide: convert (void *)devfdt_get_addr() to dev_read_addr_ptr() Use the _ptr suffixed variant instead of casting. Also, convert it to dev_read_addr_ptr(), which is safe to CONFIG_OF_LIVE. One curious part is an error check like follows in drivers/watchdog/omap_wdt.c: priv->regs = (struct wd_timer *)devfdt_get_addr(dev); if (!priv->regs) return -EINVAL; devfdt_get_addr() returns FDT_ADDR_T_NONE (i.e. -1) on error. So, this code does not catch any error in DT parsing. dev_read_addr_ptr() returns NULL on error, so this error check will work.
