+Subject: misc: alcor_pci: fix inverted branch condition
+
+From: Tong Zhang <ztong0001@gmail.com>
+
+commit 281e468446994a7672733af2bf941f4110d4a895 upstream.
+
+This patch fixes a trivial mistake that I made in the previous attempt
+in fixing the null bridge issue. The branch condition is inverted and we
+should call alcor_pci_find_cap_offset() only if bridge is not null.
+

+Subject: scsi: scsi_dh_alua: Fix signedness bug in alua_rtpg()

+
+commit 80927822e8b6be46f488524cd7d5fe683de97fc4 upstream.
+
+The "retval" variable needs to be signed for the error handling to work.
