Xin Xiong e895e067d7 spi: uniphier: fix reference count leak in uniphier_spi_probe() ... commit 37c2c83ca4f1ef4b6908181ac98e18360af89b42 upstream. 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.
