Description
In the Linux kernel, the following vulnerability has been resolved: spi: qup: Don't skip cleanup in remove's error path Returning early in a platform driver's remove callback is wrong. In this case the dma resources are not released in the error path. this is never retried later and so this is a permanent leak. To fix this, only skip hardware disabling if waking the device fails.
