In the Linux kernel, the following vulnerability has been resolved:
mtd: rawnand: pl353: fix probe resource allocation
During probe(), the devm_ioremap() is called with the parent device instead of the current one. So when the module is unloaded, the register area isnt released.
Target the pl35x device in the devm_ioremap() instead of its parent.
