CVE-2023-53758

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> spi: atmel-quadspi: Free resources even if runtime resume failed in .remove()<br /> <br /> An early error exit in atmel_qspi_remove() doesn&amp;#39;t prevent the device<br /> unbind. So this results in an spi controller with an unbound parent<br /> and unmapped register space (because devm_ioremap_resource() is undone).<br /> So using the remaining spi controller probably results in an oops.<br /> <br /> Instead unregister the controller unconditionally and only skip hardware<br /> access and clk disable.<br /> <br /> Also add a warning about resume failing and return zero unconditionally.<br /> The latter has the only effect to suppress a less helpful error message by<br /> the spi core.
