Description
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.
Affected configurations
• linux linux kernel (>= 4.20 < 5.4.118)
• linux linux kernel (>= 5.5 < 5.10.36)
• linux linux kernel (>= 5.11 < 5.11.20)
