Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: s3c64xx: fix NULL-deref on driver unbind
A change moving DMA channel allocation from probe() back to s3c64xx_spi_prepare_transfer() failed to remove the corresponding deallocation from remove().
Drop the bogus DMA channel release from remove() to avoid triggering a NULL-pointer dereference on driver unbind.
This issue was flagged by Sashiko when reviewing a controller deregistration fix.
