Summary
mlxsw: minimal: fix potential memory leak in mlxsw_m_linecards_init
Details

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

mlxsw: minimal: fix potential memory leak in mlxswmlinecards_init

The line cards array is not freed in the error path of mlxswmlinecardsinit(), which can lead to a memory leak. Fix by freeing the array in the error path, thereby making the error path identical to mlxswmlinecardsfini().
