The variable ret is being initialized with a value that is never read,
the assignment is redundant and can be removed.

Variable ret is being assigned with a value that is never read as
there is return statement immediately afterwards. The assignment
is redundant and hence can be removed.

Not related to this patch, but it would be nicer to return NULL instead
of tgt. It's the same but the literal is nicer. No need for the error
message after a kmalloc failure either.
tgt = kzalloc(sizeof(*tgt), GFP_KERNEL);
if (!tgt)
return NULL;
