Subject: [PATCH] powerpc/powernv/npu: Allocate enough memory in pnv_try_setup_npu_table_group()

From: Dan Carpenter <[email-masked]>
Date: Wed, 9 Jan 2019 13:23:29 +0300

There is a typo so we accidentally allocate enough memory for a pointer
when we wanted to allocate enough for a struct.

Fixes: 0bd971676e68 ("powerpc/powernv/npu: Add compound IOMMU groups")
