DEBIAN-CVE-2026-23068

In the Linux kernel, the following vulnerability has been resolved:  spi: spi-sprd-adi: Fix double free in probe error path  The driver currently uses spiallochost() to allocate the controller but registers it using devmspiregistercontroller().  If devmregisterrestarthandler() fails, the code jumps to the putctlr label and calls spicontrollerput(). However, since the controller was registered via a devm function, the device core will automatically call spicontrollerput() again when the probe fails. This results in a double-free of the spicontroller structure.  Fix this by switching to devmspiallochost() and removing the manual spicontroller_put() call.
