Descriptions

In the Linux kernel, the following vulnerability has been resolved:

mmc: uniphier-sd: Fix a resource leak in the remove function

A 'tmio_mmc_host_free()' call is missing in the remove function, in order
to balance a 'tmio_mmc_host_alloc()' call in the probe.
This is done in the error handling path of the probe, but not in the remove
function.

Add the missing call.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mmc: uniphier-sd: corrige una fuga de recursos en la función de eliminación Falta una llamada 'tmio_mmc_host_free()' en la función de eliminación, para equilibrar un 'tmio_mmc_host_alloc()' llamar a la sonda. Esto se hace en la ruta de manejo de errores de la sonda, pero no en la función de eliminación. Agrega la llamada faltante.
