In the Linux kernel, the following vulnerability has been resolved: spi: wpcm-fiu: Fix potential NULL pointer dereference in wpcm_fiu_probe() platform_get_resource_byname() can return NULL, which would cause a crash when passed the pointer to resource_size(). Move the fiu->memory_size assignment after the error check for devm_ioremap_resource() to prevent the potential NULL pointer dereference.

A flaw was found in the Linux kernel. A null pointer dereference in the `wpcm-fiu` Serial Peripheral Interface (SPI) driver, specifically when `platform_get_resource_byname()` returns a null value, could lead to a system crash. This vulnerability could allow a local attacker to cause a Denial of Service (DoS).
