2017-02-28drm: Introduce drm_property_blob_{get,put}()Thierry Reding
For consistency with other reference counting APIs in the kernel, add drm_property_blob_get() and drm_property_blob_put() to reference count DRM blob properties. Compatibility aliases are added to keep existing code working. To help speed up the transition, all the instances of the old functions in the DRM core are already replaced in this commit. A semantic patch is provided that can be used to convert all drivers to the new helpers.

2016-10-01Coccinelle: pm_runtime: ensure relevance of pm_runtime reportsJulia Lawall
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.

2016-04-12debugfs, coccinelle: check for obsolete DEFINE_SIMPLE_ATTRIBUTE() usageNicolai Stange
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.

As indicated by Sekhar in [1], there seems to be a tendency to use IS_ERR_VALUE to check the error result for pm_runtime_* functions which make no sense considering commit c48cd65 (ARM: OMAP: use consistent error checking) - the error values can either be < 0 for error OR 0, 1 in cases where we have success. So, setup a coccinelle script to help identify the same.

2013-01-22lib: devres: Introduce devm_ioremap_resource()Thierry Reding
The devm_request_and_ioremap() function is very useful and helps avoid a whole lot of boilerplate. However, one issue that keeps popping up is its lack of a specific error code to determine which of the steps that it performs failed. Furthermore, while the function gives an example and suggests what error code to return on failure, a wide variety of error codes are used throughout the tree. In an attempt to fix these problems, this patch adds a new function that drivers can transition to. The devm_ioremap_resource() returns a pointer to the remapped I/O memory on success or an ERR_PTR() encoded error code on failure. Callers can check for failure using IS_ERR() and determine its cause by extracting the error code using PTR_ERR(). devm_request_and_ioremap() is implemented as a wrapper around the new API and return NULL on failure as before. This ensures that backwards compatibility is maintained until all users have been converted to the new API, at which point the old devm_request_and_ioremap() function should be removed. A semantic patch is included which can be used to convert from the old devm_request_and_ioremap() API to the new devm_ioremap_resource() API. Some non-trivial cases may require manual intervention, though.
