Descriptions

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.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: spi: uniphier: corrige la fuga del recuento de referencias en uniphier_spi_probe() El problema ocurre en varias rutas de error en uniphier_spi_probe(). Cuando dma_get_slave_caps() o devm_spi_register_master() devuelven un código de error, la función se olvida de disminuir el recuento de los objetos `dma_rx` y `dma_tx`, lo que puede provocar fugas de recuento. Corríjalo disminuyendo el recuento de referencias de objetos específicos en esas rutas de error.
