Subject: [PATCH] [IPSEC]: Fix crypto_alloc_comp error checking
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

The function crypto_alloc_comp returns an errno instead of NULL
to indicate error.  So it needs to be tested with IS_ERR.

This is based on a patch by Vicenç Beltran Querol.
