2017-02-12genirq/devres: Use dev_name(dev) as default for devnameHeiner Kallweit1-2/+8
Allow the devname parameter to be NULL and use dev_name(dev) in this case. This should be an appropriate default for most use cases.

2015-05-13genirq: devres: Fix testing return value of request_any_context_irq()Axel Lin1-2/+2
request_any_context_irq() returns a negative value on failure. It returns either IRQC_IS_HARDIRQ or IRQC_IS_NESTED on success. So fix testing return value of request_any_context_irq(). Also fixup the return value of devm_request_any_context_irq() to make it consistent with request_any_context_irq().

2014-08-28genirq: fix reference in devm_request_threaded_irq commentEmilio López1-1/+1
It should be request_threaded_irq, not request_irq [jkosina@suse.cz: not that it would matter, as both have the same set of arguments anyway, but for sake of consistency ...] Signed-off-by: Emilio López <emilio@elopez.com.ar> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2014-02-09genirq: Add devm_request_any_context_irq()Stephen Boyd1-0/+45
Some drivers use request_any_context_irq() but there isn't a devm_* function for it. Add one so that these drivers don't need to explicitly free the irq on driver detach.

2011-07-26devres: fix possible use after freeMaxin B John1-1/+1
devres uses the pointer value as key after it's freed, which is safe but triggers spurious use-after-free warnings on some static analysis tools. Rearrange code to avoid such warnings.

2008-04-29kernel: explicitly include required header files under kernel/Robert P. J. Day1-0/+1
Following an experimental deletion of the unnecessary directive #include <linux/slab.h> from the header file <linux/percpu.h>, these files under kernel/ were exposed as needing to include one of <linux/slab.h> or <linux/gfp.h>, so explicit includes were added where necessary.

2007-02-11[PATCH] sort the devres mess outAl Viro1-0/+88
* Split the implementation-agnostic stuff in separate files. * Make sure that targets using non-default request_irq() pull kernel/irq/devres.o * Introduce new symbols (HAS_IOPORT and HAS_IOMEM) defaulting to positive; allow architectures to turn them off (we needed these symbols anyway for dependencies of quite a few drivers). * protect the ioport-related parts of lib/devres.o with CONFIG_HAS_IOPORT.
