2009-12-10dell-laptop: create a platform device as a parent for the rfkill devices etc.Alan Jenkins
dell-laptop may not need to export any sysfs files, but it should still create a platform device as a parent for the rfkill and backlight devices. Otherwise sysfs will display these as "virtual" devices, with no connection to either physical hardware or the dell-laptop module. Apparently this is useful for hardware detection.

2009-12-10dell-laptop: fix rfkill memory leak on unload and failure pathsAlan Jenkins
rfkill_unregister() should always be followed by rfkill_destroy(). Signed-off-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Acked-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Len Brown <len.brown@intel.com>
2009-12-09dell-laptop: fix a use-after-free error on the failure pathAlan Jenkins
dell_setup_rfkill() already cleans up the rfkill devices on failure. So if it returns an error, we should not try to unregister the rfkill devices. Signed-off-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Acked-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Len Brown <len.brown@intel.com>
2009-12-09dell-laptop: Fix rfkill state queriesMatthew Garrett
The current code in dell-laptop is confused about the hardware rfkill state. Fix it up such that it's always reported correctly. Signed-off-by: Matthew Garrett <mjg@redhat.com> Tested-by: Tim Gardner <tim.gardner@canonical.com> Signed-off-by: Len Brown <len.brown@intel.com>

A polarity error snuck into the rfkill rewrite's dell-laptop conversion, fix it. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Tested-by: Oliver Hartkopp <oliver@hartkopp.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-06-03rfkill: rewriteJohannes Berg
This patch completely rewrites the rfkill core to address the following deficiencies: * all rfkill drivers need to implement polling where necessary rather than having one central implementation * updating the rfkill state cannot be done from arbitrary contexts, forcing drivers to use schedule_work and requiring lots of code * rfkill drivers need to keep track of soft/hard blocked internally -- the core should do this * the rfkill API has many unexpected quirks, for example being asymmetric wrt. alloc/free and register/unregister * rfkill can call back into a driver from within a function the driver called -- this is prone to deadlocks and generally should be avoided * rfkill-input pointlessly is a separate module * drivers need to #ifdef rfkill functions (unless they want to depend on or select RFKILL) -- rfkill should provide inlines that do nothing if it isn't compiled in * the rfkill structure is not opaque -- drivers need to initialise it correctly (lots of sanity checking code required) -- instead force drivers to pass the right variables to rfkill_alloc() * the documentation is hard to read because it always assumes the reader is completely clueless and contains way TOO MANY CAPS * the rfkill code needlessly uses a lot of locks and atomic operations in locked sections * fix LED trigger to actually change the LED when the radio state changes -- this wasn't done before Tested-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> [thinkpad] Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2009-03-30dmi: Let dmi_walk() users pass private dataJean Delvare
At the moment, dmi_walk() lacks flexibility, users can't pass data to the callback function. Add a pointer for private data to make this function more flexible.
