coccinelle: deref_null: avoid useless computation

2018-02-07T15:16:12+00:00

The effect of the rules ifm1, pr11, and pr12 is only used in the final rule,
which depends on context && !org && !report.  Thus these rules should only
be performed in those circumstances.

coccinelle: devm_free: reduce false positives

2018-02-07T14:53:09+00:00

Some files use both a non-devm allocation and a devm_allocation.  Don't
complain about a free when the same function contains a non-devm
allocation.

Coccinelle: memdup: drop spurious line

2018-01-29T14:06:39+00:00

The kmemdup line in the non-patch case was left over from the added kmemdup
line in the patch case.

Coccinelle: kzalloc-simple: Rename kzalloc-simple to zalloc-simple

2018-01-16T14:40:17+00:00

Rename kzalloc-simple to zalloc-simple since now the rule is not
specific to kzalloc function only, but also to many other zero memory
allocating functions specified in the rule.

Coccinelle: ifnullfree: Trim the warning reported in report mode

2018-01-16T14:39:55+00:00

Remove the unncessary part of the warning reported, in the report
mode, so that a single warning produced does not exceed more than line
and hence improve readability of the warnings produced in the subsequent
reports to a file.

Coccinelle: alloc_cast: Add more memory allocating functions to the list

2018-01-16T14:38:53+00:00

Add more memory allocating functions that are frequently used in the
kernel code to the existing list and remove the useless casts where
it is unnecessary.

But preserve those casts having __attribute__ such as __force, __iomem,
etc. which are used by Sparse in the static analysis of the code.

Also remove two blank lines at EOF.

Coccinelle: array_size: report even if include is missing

2018-01-16T14:38:52+00:00

Rule r does not depend on rule i (which is the include of
linux/kernel.h) so the output should not depend on i in
org and report mode.

Coccinelle: kzalloc-simple: Add all zero allocating functions

2018-01-16T14:38:09+00:00

There are many instances where memory is allocated using regular
allocator functions immediately followed by setting the allocated
memory to 0 value using memset.

We already have zero memory allocator functions to set the memory to
0 value instead of manually setting it using memset.

Therefore, use zero memory allocating functions instead of regular
memory allocators followed by memset 0 to remove redundant memset and
make the code more cleaner and also reduce the code size.

Coccinelle: Remove setup_timer.cocci

2017-11-21T23:57:11+00:00

Both the init_timer() and timer_setup() APIs have been removed. This
script will not be needed any more.
