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.

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

coccinelle: replace 0/1 with false/true in functions returning bool

2013-08-13T20:43:41Z

This semantic patch replaces "return {0,1};" with "return {false,true};" in functions returning bool. Signed-off-by: Rasmus Villemoes Acked-by: Julia Lawall Signed-off-by: Michal Marek

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

2013-02-22T13:26:00Z

Semantic patch (http://coccinelle.lip6.fr/) to check for constants that are added but are used elsewhere as bitmasks. Signed-off-by: Julia Lawall Signed-off-by: Michal Marek

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.

scripts/coccinelle/misc/warn.cocci: use WARN

2012-12-09T14:29:07Z

Use WARN(1,...) rather than printk followed by WARN(1). Signed-off-by: Julia Lawall Signed-off-by: Michal Marek

scripts/coccinelle: Find threaded IRQs requests which are missing IRQF_ONESHOT

2012-07-13T13:57:31Z

Since commit 1c6c69525b ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail. This semantic patch will help to statically identify (and fix) such cases. Signed-off-by: Lars-Peter Clausen Signed-off-by: Julia Lawall Signed-off-by: Michal Marek
