Huai-Yuan Liu 4b31a22609 spi: mchp-pci1xxx: Fix a possible null pointer dereference in pci1xxx_spi_probe 
[ Upstream commit 1f886a7bfb ]

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.

Fixes: 1cc0cbea71 ("spi: microchip: pci1xxxx: Add driver for SPI controller of PCI1XXXX PCIe switch")
