CVE-2022-48723

Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: uniphier: fix reference count leak in uniphier_spi_probe()
The issue happens in several error paths in uniphier_spi_probe().
When either dma_get_slave_caps() or devm_spi_register_master() returns
an error code, the function forgets to decrease the refcount of both
dma_rx and dma_tx objects, which may lead to refcount leaks.
Fix it by decrementing the reference count of specific objects in those error paths.
