scripts/coccinelle: find constant additions that could be bit ors

scripts/coccinelle/misc/memcpy-assign.cocci: Replace memcpy with struct assignment

2013-02-22T10:22:18Z

There are error-prone memcpy() that can be replaced by struct assignment that are type-safe and much easier to read. This semantic patch looks for memcpy() that can be replaced by struct assignment. Inspired by patches sent by Ezequiel Garcia Signed-off-by: Peter Senna Tschudin Signed-off-by: Michal Marek

scripts/coccinelle/misc/semicolon.cocci: Add unneeded semicolon test

2013-01-24T11:10:38Z

This semantic patch looks for semicolons that can be removed without changing the semantics of the code. The confidence is moderate because there are some false positives on cases like: b/drivers/mmc/host/cb710-mmc.c:589 break; case MMC_POWER_UP: default: - /* ignore */; } There are 37 patches accepted reported by this semantic patch and more than 300 fixes to be applied.

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
