commit 8d81ae05d0176da1c54aeaed697fa34be5c5575e upstream.
As of perl 5, version 26, subversion 0 (v5.26.0) some new warnings have
occurred when running checkpatch.
Unescaped left brace in regex is deprecated here (and will be fatal in
Perl 5.30), passed through in regex; marked by <-- HERE in m/^(.\s*){
<-- HERE \s*/ at scripts/checkpatch.pl line 3544.

Unescaped left brace in regex is deprecated here (and will be fatal in
Perl 5.30), passed through in regex; marked by <-- HERE in
m/^(\+.*(?:do|\))){ <-- HERE / at scripts/checkpatch.pl line 4374.
It seems perfectly reasonable to do as the warning suggests and simply
escape the left brace in these three locations.

Add missing support for the devm_request_threaded_irq in
the rules of context, report and org modes.
Misc:

To be consistent with other scripts, change confidence level
of the script to 'Moderate'.

(cherry picked from commit 35b303ae361611a6b418e385fee06fa08732b2e6)
Currently because of the left associativity of the operators, pattern
IRQF_ONESHOT | flags does not match with the pattern when we have more
than one flag after the disjunction. This eventually results in giving
false positives by the script. This patch eliminates these FPs by
improving the rule.

pm_runtime.cocci starts with one rule that searches for a variety of
functions calls, followed by various rules that report errors. Previously,
the only connection between the first rule and the rest was to check that
the first rule had matched somewhere. Change the rules to propagate a
position from the first rule to the others, to make sure that the sites
reported on are the same as the sites that were identified as having the
relevant functions.

(cherry picked from commit cc65e823363834a7ff0a2eca9bef2bbef64135f7)
krealloc() must not be used against devm_*() allocated
memory regions:
- if a bigger memory is to be allocated, krealloc() and
__krealloc() could return a different pointer than the
one given to them, creating a memory region which is not
managed, thus it will not be automatically released on
device removal.
- if a bigger memory is to be allocated, krealloc() could
kfree() the managed memory region which is passed to it.
The old pointer is left registered as a resource for the
device. On device removal, this dangling pointer will be
used and an unrelated memory region could be released.
- if the requested size is equal to 0, krealloc() can also
just behave like kfree(). Here too, the old pointer is
kept associated with the device. On device removal, this
invalid pointer will be used and an unrelated memory
region could be released.
For all these reasons, krealloc() must not be used on a
pointer returned by devm_*() functions.

(cherry picked from commit b7b2ee41f300b69c67c798df0cd5b8648bcb26a3)
Since commit 3ef0e5ba46 ('slab: introduce kzfree()'),
kfree() is no more the only function to be considered:
kzfree() should be recognized too.
In particular, kzfree() must not be called on memory
allocated through devm_*() functions.

function calls as a argument.
Also, for the patch mode third rule should behave same as
second rule with arguments reversed. So, change that as well.

The header mentions this check depends on personal taste. I agree.
Running coccicheck on patches before I apply them, this SmPL produced
enough false positives for me that I'd rather see it removed.

(cherry picked from commit 8f551befa2269dc244bcfbcad795132f833cb71c)
Unsigned expressions cannot be lesser than zero. Presence of comparisons
'unsigned (<|<=|>|>=) 0' often indicates a bug, usually wrong type of variable.
The patch beside finding such comparisons tries to eliminate false positives,
mainly by bypassing range checks.
gcc can detect such comparisons also using -Wtype-limits switch, but it warns
also in correct cases, making too much noise.
