ACPI-6.3 corresponds to when hmat revision was bumped from

deprecated and made reserved.
As such in revision 2+ we shouldn't be testing this flag.

This fixes a kernel panic (read overflow) on memcpy when
FORTIFY_SOURCE is enabled.
The computed size of memcpy args are:
- p_size (dst): 4294967295 = (size_t) -1
- q_size (src): 1
- size (len): 8
Additionally, the memory is marked as __iomem, so one of
the memcpy_* functions should be used for r
When a user process exits, the kernel cleans up the mm_struct of the user

Reference counters are preferred to use refcount_t instead of

This is because the implementation of refcount_t can prevent

The existing code uses an OR operation which would mix the original
divider setting with the new one, resulting in an invalid
configuration that can make codecs hang.
Add the mask definition and use cdns_updatel to update divider

On most hardware platforms, SoundWire interfaces are pin-muxed with
other interfaces (typically DMIC or I2S) and the status of each link
needs to be checked at boot time.

A number of variables don't need to be initialized.
In a couple of cases where we loop on a list of runtimes, the code
handling of the 'bus' variable leads to warnings that it may not be

Despite extensive testing of 885bd765963b ("phy: qcom-qmp: Correct

the PHY gets ready. Similar to the prior bug with UFS the code will

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct touchpad_protocol {
...
struct tp_fingerfingers[0];
};

TMC etr always copies all available data to perf aux buffer, which
may exceed the available space in perf aux buffer. It isn't suitable
for not-snapshot mode, because:
1) It may overwrite previously written data.
2) It may make the perf_event_mmap_page->aux_head report having more

The function media_entity_get_fwnode_pad() can be passed the
const local_fwnode member from a struct fwnode_endpoint, so
the fwnode argument should be a const pointer. Change the
