+Subject: ALSA: cs4236: fix error return comparison of an unsigned integer
+
+From: Colin Ian King <colin.king@canonical.com>
+
+commit d60229d84846a8399257006af9c5444599f64361 upstream.
+
+The return from pnp_irq is an unsigned integer type resource_size_t
+and hence the error check for a positive non-error code is always
+going to be true. A check for a non-failure return from pnp_irq
+should in fact be for (resource_size_t)-1 rather than >= 0.
+
+Addresses-Coverity: ("Unsigned compared against 0")
+Fixes: a9824c868a2c ("[ALSA] Add CS4232 PnP BIOS support")

+Subject: exit: panic before exit_mm() on global init exit
+
+From: chenqiwu <chenqiwu@xiaomi.com>
+
+commit 43cf75d96409a20ef06b756877a2e72b10a026fc upstream.
+
+Currently, when global init and all threads in its thread-group have exited
+we panic via:
+do_exit()
+-> exit_notify()
+ -> forget_original_parent()
+ -> find_child_reaper()
+This makes it hard to extract a useable coredump for global init from a
+kernel crashdump because by the time we panic exit_mm() will have already
+released global init's mm.
+This patch moves the panic futher up before exit_mm() is called. As was the
+case previously, we only panic when global init and all its threads in the
+thread-group have exited.
