2020-02-19ASoC: fix card registration regression.Jerome Brunet
This reverts commit b2354e4009a773c00054b964d937e1b81cb92078. This change might have been desirable to ensure the uniqueness of the component name. It would have helped to better support linux devices which register multiple components, something is which more common than initially thought. However, some card driver are directly using dev_name() to fill the component names of the dai_link which is a problem if want to change the way ASoC generates the component names. Until we figure out the appropriate way to deal with this, revert the change and keep the names as they were. There might be a couple of warning related to debugfs (which were already present before the change) but it is still better than breaking working audio cards.

2020-02-19ASoC: pcm: Fix possible buffer overflow in dpcm state sysfs outputTakashi Iwai
dpcm_show_state() invokes multiple snprintf() calls to concatenate formatted strings on the fixed size buffer. The usage of snprintf() is supposed for avoiding the buffer overflow, but it doesn't work as expected because snprintf() doesn't return the actual output size but the size to be written.

2020-02-19iommu/arm-smmu: Restore naming of driver parameter prefixWill Deacon
Extending the Arm SMMU driver to allow for modular builds changed KBUILD_MODNAME to be "arm_smmu_mod" so that a single module could be built from the multiple existing object files without the need to rename any source files. This inadvertently changed the name of the driver parameters, which may lead to runtime issues if bootloaders are relying on the old names for correctness (e.g. "arm-smmu.disable_bypass=0"). Although MODULE_PARAM_PREFIX can be overridden to restore the old naming for builtin parameters, only the new name is matched by modprobe and so loading the driver as a module would cause parameters specified on the kernel command line to be ignored. Instead, rename "arm_smmu_mod" to "arm_smmu". Whilst it's a bit of a bodge, this allows us to create a single module without renaming any files and makes use of the fact that underscores and hyphens can be used interchangeably in parameter names.

2020-02-19dmaengine: ti: k3-udma: Workaround for RX teardown with stale data in peerPeter Ujfalusi
When a channel is asked to be stopped (teardown) and we do not have active descriptor to receive stale data buffered on the remote side then the teardown will not complete as UDMA needs a descriptor to be able to flush out the DMA pipe. The peer is trying to push the data to UDMA in teardown, but UDMA is pushing back because it has no descriptor which would allow it to drain the data. The workaround is to create 1K 'trashcan' to receive the discarded data and set up descriptors for packet and TR mode channels. When a channel is stopped and there is no active descriptor then a descriptor is pushed to the ring for UDMA before the teardown is initiated.

2020-02-19btrfs: fix bytes_may_use underflow in prealloc error condtitionJosef Bacik
I hit the following warning while running my error injection stress testing: WARNING: CPU: 3 PID: 1453 at fs/btrfs/space-info.h:108 btrfs_free_reserved_data_space_noquota+0xfd/0x160 [btrfs] RIP: 0010:btrfs_free_reserved_data_space_noquota+0xfd/0x160 [btrfs] Call Trace: btrfs_free_reserved_data_space+0x4f/0x70 [btrfs] __btrfs_prealloc_file_range+0x378/0x470 [btrfs] elfcorehdr_read+0x40/0x40 ? elfcorehdr_read+0x40/0x40 ? btrfs_commit_transaction+0xca/0xa50 [btrfs] ? dput+0xb4/0x2a0 ? btrfs_log_dentry_safe+0x55/0x70 [btrfs] ? btrfs_sync_file+0x30e/0x420 [btrfs] ? do_fsync+0x38/0x70 ? __x64_sys_fdatasync+0x13/0x20 ? do_syscall_64+0x5b/0x1b0 ? entry_SYSCALL_64_after_hwframe+0x44/0xa9 This happens if we fail to insert our reserved file extent. At this point we've already converted our reservation from ->bytes_may_use to ->bytes_reserved. However once we break we will attempt to free everything from [cur_offset, end] from ->bytes_may_use, but our extent reservation will overlap part of this. Fix this problem by adding ins.offset (our extent allocation size) to cur_offset so we remove the actual remaining part from ->bytes_may_use. I validated this fix using my inject-error.py script python inject-error.py -o should_fail_bio -t cache_save_setup -t \ __btrfs_prealloc_file_range \ -t insert_reserved_file_extent.constprop.0 \ -r "-5" ./run-fsstress.sh where run-fsstress.sh simply mounts and runs fsstress on a disk.

2020-02-19btrfs: handle logged extent failure properlyJosef Bacik
If we're allocating a logged extent we attempt to insert an extent record for the file extent directly. We increase space_info->bytes_reserved, because the extent entry addition will call btrfs_update_block_group(), which will convert the ->bytes_reserved to ->bytes_used. However if we fail at any point while inserting the extent entry we will bail and leave space on ->bytes_reserved, which will trigger a WARN_ON() on umount. Fix this by pinning the space if we fail to insert, which is what happens in every other failure case that involves adding the extent entry.
