+Subject: ALSA: hda: avoid write to STATESTS if controller is in reset
+
+From: Kai Vehmanen <kai.vehmanen@linux.intel.com>
+
+[ Upstream commit b37a15188eae9d4c49c5bb035e0c8d4058e4d9b3 ]
+
+The snd_hdac_bus_reset_link() contains logic to clear STATESTS register
+before performing controller reset. This code dates back to an old
+bugfix in commit e8a7f136f5ed ("[ALSA] hda-intel - Improve HD-audio
+codec probing robustness"). Originally the code was added to
+azx_reset().
+
+The code was moved around in commit a41d122449be ("ALSA: hda - Embed bus
+into controller object") and ended up to snd_hdac_bus_reset_link() and
+called primarily via snd_hdac_bus_init_chip().
+
+The logic to clear STATESTS is correct when snd_hdac_bus_init_chip() is
+called when controller is not in reset. In this case, STATESTS can be
+cleared. This can be useful e.g. when forcing a controller reset to retry
+codec probe. A normal non-power-on reset will not clear the bits.
+
+However, this old logic is problematic when controller is already in
+reset. The HDA specification states that controller must be taken out of
+reset before writing to registers other than GCTL.CRST (1.0a spec,
+3.3.7). The write to STATESTS in snd_hdac_bus_reset_link() will be lost
+if the controller is already in reset per the HDA specification mentioned.
+
+This has been harmless on older hardware. On newer generation of Intel
+PCIe based HDA controllers, if configured to report issues, this write
+will emit an unsupported request error. If ACPI Platform Error Interface
+(APEI) is enabled in kernel, this will end up to kernel log.
+
+Fix the code in snd_hdac_bus_reset_link() to only clear the STATESTS if
+the function is called when controller is not in reset. Otherwise
+clearing the bits is not possible and should be skipped.

+Subject: ALSA: hda: intel: Allow repeatedly probing on codec configuration
+ errors
+
+From: Takashi Iwai <tiwai@suse.de>
+
+[ Upstream commit c0f1886de7e173865f1a0fa7680a1c07954a987f ]
+
+It seems that a few recent AMD systems show the codec configuration
+errors at the early boot, while loading the driver at a later stage
+works magically. Although the root cause of the error isn't clear,
+it's certainly not bad to allow retrying the codec probe in such a
+case if that helps.
+
+This patch adds the capability for retrying the probe upon codec probe
+errors on the certain AMD platforms. The probe_work is changed to a
+delayed work, and at the secondary call, it'll jump to the codec
+probing.
+
+Note that, not only adding the re-probing, this includes the behavior
+changes in the codec configuration function. Namely,
+snd_hda_codec_configure() won't unregister the codec at errors any
+longer. Instead, its caller, azx_codec_configure() unregisters the
+codecs with the probe failures *if* any codec has been successfully
+configured. If all codec probe failed, it doesn't unregister but let
+it re-probed -- which is the most case we're seeing and this patch
+tries to improve.
+
+Even if the driver doesn't re-probe or give up, it will go to the
+"free-all" error path, hence the leftover codecs shall be disabled /
+deleted in anyway.

+
+From: Filipe Manana <fdmanana@suse.com>
+
+[ Upstream commit 77a5b9e3d14cbce49ceed2766b2003c034c066dc ]
+
+Currently inode_in_dir() ignores errors returned from
+btrfs_lookup_dir_index_item() and from btrfs_lookup_dir_item(), treating
+any errors as if the directory entry does not exists in the fs/subvolume
+tree, which is obviously not correct, as we can get errors such as -EIO
+when reading extent buffers while searching the fs/subvolume's tree.
+
+Fix that by making inode_in_dir() return the errors and making its only
+caller, add_inode_ref(), deal with returned errors as well.

+Subject: Input: snvs_pwrkey - add clk handling
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
+
+[ Upstream commit d997cc1715df7b6c3df798881fb9941acf0079f8 ]
+
+On i.MX7S and i.MX8M* (but not i.MX6*) the pwrkey device has an
+associated clock. Accessing the registers requires that this clock is
+enabled. Binding the driver on at least i.MX7S and i.MX8MP while not
+having the clock enabled results in a complete hang of the machine.
+(This usually only happens if snvs_pwrkey is built as a module and the
+rtc-snvs driver isn't already bound because at bootup the required clk
+is on and only gets disabled when the clk framework disables unused clks
+late during boot.)
+
+This completes the fix in commit 135be16d3505 ("ARM: dts: imx7s: add
+snvs clock to pwrkey").

+Subject: libperf tests: Fix test_stat_cpu
+
+From: Shunsuke Nakamura <nakamura.shun@fujitsu.com>
+
+[ Upstream commit 3ff6d64e68abc231955d216236615918797614ae ]
+
+The `cpu` argument of perf_evsel__read() must specify the cpu index.
+
+perf_cpu_map__for_each_cpu() is for iterating the cpu number (not index)
+and is thus not appropriate for use with perf_evsel__read().
+
+So, if there is an offline CPU, the cpu number specified in the argument
+may point out of range because the cpu number and the cpu index are
+different.
+
+Fix test_stat_cpu().
+
+Testing it:
+
+ # make tests -C tools/lib/perf/
