Newer devices and firmware will have configurations with the flexparser but without mpls support. Testing for the flex parser capability was a mistake, the tunnel_stateless capability was intended for detecting mpls and was introduced at the same time as the flex parser capability. Otherwise userspace will be incorrectly informed that a future device supports MPLS when it does not.

[PATCH 3/4] ASoC: dpcm: allow start or stop during pause for backend

by Gyeongtaek Lee

soc_compr_trigger_fe() allows start or stop after pause_push. In dpcm_be_dai_trigger(), however, only pause_release is allowed command after pause_push. So, start or stop after pause in compress offload is always returned as error if the compress offload is used with dpcm. To fix the problem, SND_SOC_DPCM_STATE_PAUSED should be allowed for start or stop command.

[PATCH 2/4] ASoC: dapm: connect virtual mux with default value

by Gyeongtaek Lee

Since a virtual mixer has no backing registers to decide which path to connect, it will try to match with initial state. This is to ensure that the default mixer choice will be correctly powered up during initialization. Invert flag is used to select initial state of the virtual switch. Since actual hardware can't be disconnected by virtual switch, connected is better choice as initial state in many cases.

[PATCH] ext4: Do not zeroout extents beyond i_disksize

by Jan Kara

We do not want to create initialized extents beyond end of file because for e2fsck it is impossible to distinguish them from a case of corrupted file size / extent tree and so it complains like: Inode 12, i_size is 147456, should be 163840. Fix? no Code in ext4_ext_convert_to_initialized() and ext4_split_convert_extents() try to make sure it does not create initialized extents beyond inode size however they check against inode->i_size which is wrong. They should instead check against EXT4_I(inode)->i_disksize which is the current inode size on disk. That's what e2fsck is going to see in case of crash before all dirty data is written. This bug manifests as generic/456 test failure (with recent enough fstests where fsx got fixed to properly pass FALLOC_KEEP_SIZE_FL flags to the kernel) when run with dioread_lock mount option.

[PATCH AUTOSEL 5.6 01/68] cpufreq: imx6q: Fixes unwanted cpu overclocking on i.MX6ULL

by Sasha Levin

From: Christoph Niedermaier <cniedermaier(a)dh-electronics.com> [ Upstream commit 36eb7dc1bd42fe5f850329c893768ff89b696fba ] imx6ul_opp_check_speed_grading is called for both i.MX6UL and i.MX6ULL. Since the i.MX6ULL was introduced to a separate ocotp compatible node later, it is possible that the i.MX6ULL has also dtbs with "fsl,imx6ull-ocotp". On a system without nvmem-cell speed grade a missing check on this node causes a driver fail without considering the cpu speed grade. This patch prevents unwanted cpu overclocking on i.MX6ULL with compatible node "fsl,imx6ull-ocotp" in old dtbs without nvmem-cell speed grade.
