Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
spi: ch341: fix devres lifetime<br />
<br />
USB drivers bind to USB interfaces and any device managed resources<br />
should have their lifetime tied to the interface rather than parent USB<br />
device. This avoids issues like memory leaks when drivers are unbound<br />
without their devices being physically disconnected (e.g. on probe<br />
deferral or configuration changes).<br />
<br />
Fix the controller and driver data lifetime so that they are released<br />
on driver unbind.<br />
<br />
Note that this also makes sure that the SPI controller is placed<br />
correctly under the USB interface in the device tree.
