[SCSI] scsi: lpfc error path fix
Add kmalloc failure check and fix the loop on error path. Without the patch pool element at index [0] will not be freed. Signed-off-by: Mariusz Kozlowski <m.kozlowski@tuxland.pl> Acked-by: James Smart <James.Smart@Emulex.Com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
