2021-12-23platform/x86: intel_pmc_core: fix memleak on registration failureJohan Hovold
In case device registration fails during module initialisation, the platform device structure needs to be freed using platform_device_put() to properly free all resources (e.g. the device name).

There are some chances that the actual base of hardware is different from the value recorded by driver, so we have to reset the variable of ocp_base to sync it. Set ocp_base to -1.

If a traffic class to priority mapping is configured on the netdevice (with mqprio for example ...), it won't be considered for CPU injected headers.

2021-12-23ext4: fix i_version handling on remountLukas Czerner
i_version mount option is getting lost on remount. This is because the 'i_version' mount option differs from the util-linux mount option 'iversion', but it has exactly the same functionality. We have to specifically notify the vfs that this is what we want by setting appropriate flag in fc->sb_flags. Fix it and as a result we can remove *flags argument from __ext4_remount(); do the same for __ext4_fill_super(). In addition set out to deprecate ext4 specific 'i_version' mount option in favor or 'iversion' by kernel version 5.20.

2021-12-23mtd: spi-nor: micron-st: write 2 bytes when disabling Octal DTR modePratyush Yadav
The Octal DTR configuration is stored in the CFR0V register. This register is 1 byte wide. But 1 byte long transactions are not allowed in 8D-8D-8D mode. The next byte address contains the CFR1V register, which contains the number of dummy cycles. This is very fortunate since the enable path changes the value of this register. Reset the value to its default when disabling Octal DTR mode. This way, both changes to the flash state made when enabling can be reverted in one single transaction.

2021-12-23mtd: spi-nor: core: use 2 data bytes for template opsPratyush Yadav
The template ops used in spi_nor_spimem_check_pp() and spi_nor_spimem_check_readop() currently set the data phase to 1 byte long. This is problematic for 8D-8D-8D protocol where odd length data phase is invalid since one cycle transfers 2 bytes and odd number of bytes would mean half a cycle is left over. This could result in a controller rejecting the op as "not supported" even though it actually supports the protocol. Change the data length to 2 bytes in these templates. One might argue that this should only be done for 8D-8D-8D operations but when talking about these templates, there is no functional difference between one and two bytes, even in STR modes.

2021-12-23drm/i915: Use trylock instead of blocking lock for __i915_gem_free_objects.Maarten Lankhorst
Convert free_work into delayed_work, similar to ttm to allow converting the blocking lock in __i915_gem_free_objects to a trylock. Unlike ttm, the object should already be idle, as it's kept alive by a reference through struct i915_vma->active, which is dropped after all vma's are idle. Because of this, we can use a no wait by default, or when the lock is contested, we use ttm's 10 ms. The trylock should only fail when the object is sharing it's resv with other objects, and typically objects are not kept locked for a long time, so we can safely retry on failure.
