2015-04-15scripts/coccinelle/misc/bugon.cocci: update bug_on conversion warningFabian Frederick1-1/+1
if()/BUG conversion to BUG_ON must be avoided when there's side effect in condition. The reason being BUG_ON won't execute the condition when CONFIG_BUG is not defined. Inspired-by: J.

2015-03-25irqf_oneshot.cocci: add check of devm_request_threaded_irq()Valentin Rothberg1-0/+24
Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail. Until now, this coccinelle script only checked request_threaded_irq(). However, the counterpart devm function (see kernel/irq/devres.c) is also affected by the missing flag which can be detected with this patch.

2013-01-22lib: devres: Introduce devm_ioremap_resource()Thierry Reding1-0/+90
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.
