[PATCH][Resend] SCSI, target, loopback: Fix memory leak intcm_loop_make_scsi_hba()

From: Jesper Juhl
Date: Mon Jun 27 2011 - 18:05:52 EST


There is a memory leak in tcm_loop_make_scsi_hba().

If all the strstr() calls return NULL and we end up at
return ERR_PTR(-EINVAL);
then we'll be leaking the memory previously allocated to tl_hba as
that variable goes out of scope.

This patch should fix the leak.
