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.
I generated this commit by the following command:
$ find . -name .git -prune -o -name '*.[ch]' -type f -print | \
xargs sed -i -e 's/([^*)]*\*)devfdt_get_addr(/dev_read_addr_ptr(/'
I manually fixed drivers/usb/host/ehci-mx6.c
