* cpuidle-kirkwood.c: simplify use of devm_ioremap_resource()Julia Lawall2013-08-141-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource(). A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression pdev,res,n,e,e1; expression ret != 0; identifier l; @@ - res = platform_get_resource(pdev, IORESOURCE_MEM, n); ... when != res - if (res == NULL) { ... \(goto l;\|return ret;\) } ... when != res + res = platform_get_resource(pdev, IORESOURCE_MEM, n); e = devm_ioremap_resource(e1, res); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Rafael J.

* cpuidle: kirkwood: Make kirkwood_cpuidle_remove function staticJingoo Han2013-08-121-1/+1
| | | | | | | | | | | This local symbol is used only in this file. Fix the following sparse warnings: drivers/cpuidle/cpuidle-kirkwood.c:73:5: warning: symbol 'kirkwood_cpuidle_remove' was not declared. Should it be static ?

* cpuidle: add maintainer entryDaniel Lezcano2013-04-261-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently cpuidle drivers are spread across different archs. As a result, there are several different paths for cpuidle patch submissions: cpuidle core changes go through linux-pm, ARM driver changes go to the arm-soc or SoC-specific trees, sh changes go through the sh arch tree, pseries changes go through the PowerPC tree and finally intel changes go through the Len's tree while ACPI idle changes go through linux-pm. That makes it difficult to consolidate code and to propagate modifications from the cpuidle core to the different drivers. Hopefully, a movement has started to put the majority of cpuidle drivers under drivers/cpuidle like cpuidle-calxeda.c and cpuidle-kirkwood.c. Add a maintainer entry for cpuidle to MAINTAINERS to clarify the situation and to indicate to new cpuidle driver authors that those drivers should not go into arch-specific directories. The upstreaming process is unchanged: Rafael takes patches for merging into his tree, but with an Acked-by: tag from the driver's maintainer, so indicate in the drivers' headers who maintains them. The arrangement will be the same as for cpufreq.

* cpuidle: kirkwood: fix coccicheck warningsSilviu-Mihai Popescu2013-04-011-3/+3
| | | | | | | | | | | | Convert all uses of devm_request_and_ioremap() to the newly introduced devm_ioremap_resource() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages so all explicit error messages can be removed from the failure code paths.
