Descriptions

In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: denali: Use managed device resources All of the resources used by this driver has managed interfaces, so use
them. Otherwise we will get the following splat: [ 4.472703] denali-nand-pci 0000:00:05.0: timeout while waiting for irq 0x1000
[ 4.474071] denali-nand-pci: probe of 0000:00:05.0 failed with error -5
