+Subject: atm: idt77252: fix a memleak in open_card_ubr0
+
+From: Zhipeng Lu <alexious@zju.edu.cn>
+
+[ Upstream commit f3616173bf9be9bf39d131b120d6eea4e6324cb5 ]
+
+When alloc_scq fails, card->vcs[0] (i.e. vc) should be freed. Otherwise,
+in the following call chain:
+
+idt77252_init_one
+ |-> idt77252_dev_open
+ |-> open_card_ubr0
+ |-> alloc_scq [failed]
+ |-> deinit_card
+ |-> vfree(card->vcs);
+
+card->vcs is freed and card->vcs[0] is leaked.

+Subject: hwmon: (coretemp) Fix bogus core_id to attr name mapping
+
+From: Zhang Rui <rui.zhang@intel.com>
+
+[ Upstream commit fdaf0c8629d4524a168cb9e4ad4231875749b28c ]
+
+Before commit 7108b80a542b ("hwmon/coretemp: Handle large core ID
+value"), there is a fixed mapping between
+1. cpu_core_id
+2. the index in pdata->core_data[] array
+3. the sysfs attr name, aka "tempX_"
+The later two always equal cpu_core_id + 2.
+
+After the commit, pdata->core_data[] index is got from ida so that it
+can handle sparse core ids and support more cores within a package.
+
+However, the commit erroneously maps the sysfs attr name to
+pdata->core_data[] index instead of cpu_core_id + 2.
+
+As a result, the code is not aligned with the comments, and brings user
+visible changes in hwmon sysfs on systems with sparse core id.
+
+For example, before commit 7108b80a542b ("hwmon/coretemp: Handle large
+core ID value"),
+/sys/class/hwmon/hwmon2/temp2_label:Core 0
+/sys/class/hwmon/hwmon2/temp3_label:Core 1
+/sys/class/hwmon/hwmon2/temp4_label:Core 2
+/sys/class/hwmon/hwmon2/temp5_label:Core 3
+/sys/class/hwmon/hwmon2/temp6_label:Core 4
+/sys/class/hwmon/hwmon3/temp10_label:Core 8
+/sys/class/hwmon/hwmon3/temp11_label:Core 9
+after commit,
+/sys/class/hwmon/hwmon2/temp2_label:Core 0
+/sys/class/hwmon/hwmon2/temp3_label:Core 1
+/sys/class/hwmon/hwmon2/temp4_label:Core 2
+/sys/class/hwmon/hwmon2/temp5_label:Core 3
+/sys/class/hwmon/hwmon2/temp6_label:Core 4
+/sys/class/hwmon/hwmon2/temp7_label:Core 8
+/sys/class/hwmon/hwmon2/temp8_label:Core 9
+
+Restore the previous behavior and rework the code, comments and variable
+names to avoid future confusions.

+Subject: rxrpc: Fix response to PING RESPONSE ACKs to a dead call
+
+From: David Howells <dhowells@redhat.com>
+
+[ Upstream commit 6f769f22822aa4124b556339781b04d810f0e038 ]
+
+Stop rxrpc from sending a DUP ACK in response to a PING RESPONSE ACK on a
+dead call. We may have initiated the ping but the call may have beaten the
+response to completion.

+
+The cause of this issue is that when tipc_nl_bearer_add() is called with
+the TIPC_NLA_BEARER_UDP_OPTS attribute, tipc_udp_nl_bearer_add() is called
+even if the bearer is not UDP.
+
+tipc_udp_is_known_peer() called by tipc_udp_nl_bearer_add() assumes that
+the media_ptr field of the tipc_bearer has an udp_bearer type object, so
+the function goes crazy for non-UDP bearers.
+
+This patch fixes the issue by checking the bearer type before calling
+tipc_udp_nl_bearer_add() in tipc_nl_bearer_add().
+
