Coccinelle: Script to replace if and BUG with BUG_ON

2014-08-06T10:10:17+00:00

This script detects cases where BUG() follows an if condition on an
expression and replaces the if condition and BUG() with a BUG_ON having
the conditional expression of the if statement as argument.

Coccinelle: Script to detect incorrect argument to sizeof

2014-08-06T10:10:17+00:00

This makes an effort to find cases where the argument to sizeof is wrong
in memory allocation functions by checking the type of the allocated
memory when it is a double pointer and ensuring the sizeof argument takes
a pointer to the the memory being allocated. There are false positives
in cases the sizeof argument is not used in constructing the return value.

Coccinelle: Script to use ARRAY_SIZE instead of division of two sizeofs

2014-08-06T10:10:17+00:00

This script detects cases where ARRAY_SIZE can be used such as
where there is a division of sizeof the array by the sizeof its first
element or by any indexed element or the element type. It replaces the
division of the two sizeofs by ARRAY_SIZE.

Coccinelle: Script to detect cast after memory allocation

2014-08-06T10:10:17+00:00

This script detects cases of use of cast for the value returned by
kmalloc, kzalloc, kcalloc, kmem_cache_alloc, kmem_cache_zalloc,
kmem_cache_alloc_node, kmalloc_node and kzalloc_node and removes
the cast as it is not useful. This Coccinelle script replaces
drop_kmalloc_cast.cocci as it removes the casting in more limited
cases of kmalloc, kzalloc and kcalloc.

coccinelle/null: solve parse error

2014-08-06T10:10:17+00:00

This patch solves the parse-error by adding @@ . This is necessary since
Coccinelle version 1.0.0-rc20. Also, the comment is added to use a
recent version of Coccinelle.

devres: remove devm_request_and_ioremap()

2014-06-20T03:01:36+00:00

devm_request_and_ioremap() was obsoleted by the commit 7509657
("lib: devres: Introduce devm_ioremap_resource()") and has been
deprecated for a long time. So, let's remove this function.
In addition, all usages of devm_request_and_ioremap() are also
removed.

coccicheck: Add unneeded return variable test

2014-06-10T12:36:30+00:00

This semantic patch looks for variables that are initialized with a
constant, are never updated, and are only used as parameter of return.
Return the constant instead of using a variable.
