  "description": "In the Linux kernel, the following vulnerability has been resolved:  pinctrl: mcp23s08: Initialize mcp-\u003Edev and mcp-\u003Eaddr before regmap init  Regmap initialization triggers regcache_maple_populate() which attempts SPI read to populate cache. SPI read requires mcp-\u003Edev and mcp-\u003Eaddr to be set, without them, NULL pointer dereference occurs during probe.  Move initialization before mcp23s08_spi_regmap_init() call.",
