+Subject: ALSA: hda - Fix onboard audio on Intel H97/Z97 chipsets
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 77f07800cb456bed6e5c345e6e4e83e8eda62437 upstream.
+
+The recent Intel H97/Z97 chipsets need the similar setups like other
+Intel chipsets for snooping, etc. Especially without snooping, the
+audio playback stutters or gets corrupted. This fix patch just adds
+the corresponding PCI ID entry with the proper flags.

+Subject: Input: atkbd - fix keyboard not working on some LG laptops
+
+From: Sheng-Liang Song <ssl@chromium.org>
+
+commit 3d725caa9dcc78c3dc9e7ea0c04f626468edd9c9 upstream.
+
+After issuing ATKBD_CMD_RESET_DIS, keyboard on some LG laptops stops
+working. The workaround is to stop issuing ATKBD_CMD_RESET_DIS commands.
+
+In order to keep changes in atkbd driver to the minimum we check DMI
+signature and only skip ATKBD_CMD_RESET_DIS if we are running on LG
+LW25-B7HV or P1-J273B.

+Subject: Input: elantech - fix touchpad initialization on Gigabyte U2442
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+commit 36189cc3cd57ab0f1cd75241f93fe01de928ac06 upstream.
+
+The hw_version 3 Elantech touchpad on the Gigabyte U2442 does not accept
+0x0b as initialization value for r10, this stand-alone version of the
+driver: http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2
+
+Uses 0x03 which does work, so this means not setting bit 3 of r10 which
+sets: "Enable Real H/W Resolution In Absolute mode"
+
+Which will result in half the x and y resolution we get with that bit set,
+so simply not setting it everywhere is not a solution. We've been unable to
+find a way to identify touchpads where setting the bit will fail, so this
+patch uses a dmi based blacklist for this.

+From: Hans de Goede <hdegoede@redhat.com>
+
+commit 6d396ede224dc596d92d7cab433713536e68916c upstream.
+
+The T540p has a touchpad with pnp-id LEN0034, all the models with this
+pnp-id have the same min/max values, except the T540p where the values are
+slightly off. Fix them to be identical.
+
+This is a preparation patch for simplifying the quirk table.

+Subject: trace: module: Maintain a valid user count
+
+From: Romain Izard <romain.izard.pro@gmail.com>
+
+commit 098507ae3ec2331476fb52e85d4040c1cc6d0ef4 upstream.
+
+The replacement of the 'count' variable by two variables 'incs' and
+'decs' to resolve some race conditions during module unloading was done
+in parallel with some cleanup in the trace subsystem, and was integrated
+as a merge.
+
+Unfortunately, the formula for this replacement was wrong in the tracing
+code, and the refcount in the traces was not usable as a result.
+
+Use 'count = incs - decs' to compute the user count.
