In the Linux kernel, the following vulnerability has been resolved: spi:
mchp-pci1xxx: Fix a possible null pointer dereference in pci1xxx_spi_probe
In function pci1xxxx_spi_probe, there is a potential null pointer that may
be caused by a failed memory allocation by the function devm_kzalloc.
Hence, a null pointer check needs to be added to prevent null pointer
dereferencing later in the code. To fix this issue, spi_bus->spi_int[iter]
should be checked. The memory allocated by devm_kzalloc will be
automatically released, so just directly return -ENOMEM without worrying
about memory leaks.
