scripts: Coccinelle script for pm_runtime_* return checks with IS_ERR_VALUE

2014-01-03T13:39:35Z

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.

lib: devres: Introduce devm_ioremap_resource()

2013-01-22T17:41:43Z

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. Signed-off-by: Thierry Reding Cc: Arnd Bergmann Acked-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman
