drivers/net/ethernet/mellanox/mlxsw/core_linecards.c:819:18-48: WARNING: Use correct pointer type argument for sizeof

 Correct the size argument to alloc functions

Semantic patch information:
 This makes an effort to find cases where the argument to sizeof is wrong
 in memory allocation functions by checking the type of the allocated memory
 when it is a double pointer and ensuring the sizeof argument takes a pointer
 to the the memory being allocated. There are false positives in cases the
 sizeof argument is not used in constructing the return value. The result
 may need some reformatting.
