Description

mlxsw: spectrum_acl_tcam: Fix incorrect list API usage

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

mlxsw: spectrum_acl_tcam: Fix incorrect list API usage

Both the function that migrates all the chunks within a region and the

function that migrates all the entries within a chunk call

list_first_entry() on the respective lists without checking that the

lists are not empty. This is incorrect usage of the API, which leads to

the following warning [1].

Fix by returning if the lists are empty as there is nothing to migrate

in this case.
