+Subject: [PATCH] ata: libata-core: fix NULL pointer deref in
+ ata_host_alloc_pinfo()
+
+[ Upstream commit bf476fe22aa1851bab4728e0c49025a6a0bea307 ]
+
+In an unlikely (and probably wrong?) case that the 'ppi' parameter of
+ata_host_alloc_pinfo() points to an array starting with a NULL pointer,
+there's going to be a kernel oops as the 'pi' local variable won't get
+reassigned from the initial value of NULL. Initialize 'pi' instead to
+'&ata_dummy_port_info' to fix the possible kernel oops for good...
+
+Found by Linux Verification Center (linuxtesting.org) with the SVACE static
+analysis tool.
