Hi All, Firstly sorry for the huge cc list, but this series does get about. This series came out of two separate lkml threads: https://lkml.org/lkml/2011/7/13/64 http://thread.gmane.org/gmane.linux.kernel/1148513/focus=74236 Basically Rusty and I both got annoyed with yet more instances of the same cut and past ida allocation code for the very simple case of wanting a unique id for some device. Tejun helpfully joined the two threads up. Anyhow, Rusty proposed more or less the first patch here (with a name change requested by Tejun applied.) The others patches are some of the more obvious looking cases for applying this code. My original reason was for IIO but those patches will have to wait a little while for some prior changes to merge. For reference, it saves about 40 lines there so I'm happy ;) There are a number of other cases in tree that can be cleaned up in a second series once these are sorted. There are a couple of cases in here where I've carefully mangled the error codes to keep consistent with the existing code. Please can people who know those subsystems well decide on whether the mangling is necessary. All comments welcome. I expect I've broken at least one driver doing this so please take a close look. Rusty, Tejun. I kept your sign of an ack for the first patch. Could you quickly verify that's fine? Thanks, Jonathan Jonathan Cameron (7): hwmon: convert idr to ida and use ida_simple interface. hwmon: ibmaem: convert idr to ida and use ida_simple_get [SCSI] use ida_simple_get and ida_simple remove in place of boilerplate code. drm/vmwgfx: use ida_simple_get for id allocation. [SCSI] osduld: use ida_simple_get to handle id. w1: ds2760 and ds2780, use ida for id and ida_simple_get to get it. rtc: class idr converted to ida and ida_simple_get used.
