Subject: [PATCH] vdpa/sfc: fix null pointer dereference
Date: Sun, 30 Jan 2022 01:30:12 +0800	[thread overview]
Message-ID: <tencent_A1C68827F89429E24C47E05B63A440E42E05@qq.com> (raw)

When sva is null, sfc_vdpa_info(sva, ...) will cause a null
dereference. Use SFC_VDPA_GENERIC_LOG() to avoid that.
See macros sfc_vdpa_info and SFC_VDPA_GENERIC_LOG
defined in drivers/vdpa/sfc/sfc_vdpa_log.h for detail.

Fixes: 5e7596ba7cb3 ("vdpa/sfc: introduce Xilinx vDPA driver")
