Coccinelle: pm_runtime: ensure relevance of pm_runtime reports

2016-10-01T21:03:41+00:00

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.

Coccinelle: limit memdup_user transformation to GFP_KERNEL case

2016-10-01T21:03:09+00:00

Memdup_user encapsulates a memory allocation with the flag GFP_KERNEL, so
only allow this flag in the original code.

Coccinelle: setup_timer: Add space in front of parentheses

2016-04-20T07:50:53+00:00

Add space in front of the offending parentheses to silent the
parse error for older Coccinelle versions. This makes the rule
usable with all Coccinelle versions.

debugfs, coccinelle: check for obsolete DEFINE_SIMPLE_ATTRIBUTE() usage

2016-04-12T21:14:21+00:00

In order to protect against file removal races, debugfs files created via
debugfs_create_file() now get wrapped by a struct file_operations at their
opening.

If the original struct file_operations are known to be safe against removal
races by themselves already, the proxy creation may be bypassed by creating
the files through debugfs_create_file_unsafe().

In order to help debugfs users who use the common
  DEFINE_SIMPLE_ATTRIBUTE() + debugfs_create_file()
idiom to transition to removal safe struct file_operations, the helper
macro DEFINE_DEBUGFS_ATTRIBUTE() has been introduced.

Thus, the preferred strategy is to use
  DEFINE_DEBUGFS_ATTRIBUTE() + debugfs_create_file_unsafe()
now.

Introduce a Coccinelle script that searches for
DEFINE_SIMPLE_ATTRIBUTE()-defined struct file_operations handed into
debugfs_create_file(). Suggest to turn these usages into the
  DEFINE_DEBUGFS_ATTRIBUTE() + debugfs_create_file_unsafe()
pattern.

coccinelle: api: extend spatch for dropping unnecessary owner

2015-08-19T15:23:45+00:00

i2c_add_driver (through i2c_register_driver) sets the owner field so we
can drop it also from i2c drivers, just like from platform drivers.
