coccicheck: Add unneeded return variable test

2014-06-10T12:36:30Z

This semantic patch looks for variables that are initialized with a constant, are never updated, and are only used as parameter of return. Return the constant instead of using a variable. Signed-off-by: Peter Senna Tschudin Signed-off-by: Michal Marek

coccinelle: Check for missing NULL terminators in of_device_id tables

2014-06-09T21:39:16Z

Failure to terminate an of_device_id table can lead to confusing failures depending on where the compiler places the array. Add a check to make sure these tables are terminated. Thanks to Mitchel Humpherys for coming up with the pattern initially.

scripts/coccinelle: Use PTR_ERR_OR_ZERO

2014-04-08T15:27:01Z

PTR_RET is deprecated. Do not recommend its usage anymore. Use PTR_ERR_OR_ZERO instead. Signed-off-by: Sachin Kamat Signed-off-by: Michal Marek

Coccicheck: Remove memcpy to struct assignment test

2014-03-29T20:35:09Z

The Coccinelle script scripts/coccinelle/misc/memcpy-assign.cocci look for opportunities to replace a call to memcpy by a struct assignment. This patch removes memcpy-assign.cocci as it is not clear that this convention has an impact on the generated code. Signed-off-by: Peter Senna Tschudin Signed-off-by: Michal Marek

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.

scripts/coccinelle/api: remove devm_request_and_ioremap.cocci

2013-10-23T14:55:15Z

Use of this function is discouraged in favour of devm_ioremap_resource(). Don't advertise it. Signed-off-by: Wolfram Sang Acked-by: Julia Lawall Signed-off-by: Michal Marek
