2007-11-10rfkill: Fix sparse warningMichael Buesch1-0/+4
Signed-off-by: John W. Linville <linville@tuxdriver.com>
2007-11-10rfkill: Use mutex_lock() at register and add sanity checkMichael Buesch1-11/+9
Replace mutex_lock_interruptible() by mutex_lock() in rfkill_register(), as interruptible doesn't make sense there. Add a sanity check for rfkill->type, as that's used for an unchecked dereference in an array and might cause hard to debug crashes if the driver sets this to an invalid value.

2007-11-10rfkill: Use subsys_initcallMichael Buesch1-1/+1
We must use subsys_initcall, because we must initialize before a driver calls rfkill_register(). Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2007-11-10rfkill: Register LED triggers before registering switchMichael Buesch1-5/+6
Registering the switch triggers a LED event, so we must register LED triggers before the switch. This has a potential to fix a crash, depending on how the device driver initializes the rfkill data structure.

2007-10-10[RFKILL]: Add support for hardware-only rfkill buttonsMichael Buesch1-1/+6
Buttons that work directly on hardware cannot support the "user_claim" functionality. Add a flag to signal this and return -EOPNOTSUPP in this case. b43 is such a device.

2007-10-10[RFKILL]: Move rfkill_switch_all out of global headerIvo van Doorn1-1/+1
rfkill_switch_all shouldn't be called by drivers directly, instead they should send a signal over the input device. To prevent confusion for driver developers, move the function into a rfkill private header. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-10[RFKILL]: Add support for ultrawidebandIvo van Doorn1-0/+3
This patch will add support for UWB keys to rfkill, support for this has been requested by Inaky. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-10[RFKILL]: Remove IRDAIvo van Doorn1-4/+1
As Dmitry pointed out earlier, rfkill-input.c doesn't support irda because there are no users and we shouldn't add unrequired KEY_ defines. However, RFKILL_TYPE_IRDA was defined in the rfkill.h header file and would confuse people about whether it is implemented or not. This patch removes IRDA support completely, so it can be added whenever a driver wants the feature. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: David S.

2007-07-18[RFKILL]: Make state sysfs writableIvo van Doorn1-1/+1
The rfkill state Sysfs attribute should be made writable, we already pass the argument for the store handler, so we only need to update the permissions flag. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
