From: Peng Fan <[email protected]> devfdt_get_addr() returns FDT_ADDR_T_NONE(-1UL) when fail, using "!priv->regs" to check return value is wrong.
Replace devfdt_read_addr() with dev_read_addr_ptr() when retrieving the register base address. dev_read_addr_ptr() supports both live device tree and flat DT backends, avoiding direct dependency on devfdt_* helpers. Also use "void __iomem *" to replace "phys_addr_t" to avoid type casting. No functional changes.
