module_param: make bool parameters really bool (drivers & misc)

2012-01-12T23:02:20+00:00

module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

USB: convert drivers/media/* to use module_usb_driver()

2011-11-18T17:46:12+00:00

This converts the drivers in drivers/media/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.

Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

[media] rc/streamzap: fix reporting response times

2011-01-31T14:22:13+00:00

The streamzap driver has relatively low sampling resolution, and any
delays in reporting events seem to cause some minor problems for the
likes of irw when using the lirc bridge driver, resulting in a single
keypress registering as multiple independent ones, rather than as a
single press with repeats. If we call ir_raw_event_handle() more
frequently and reset the rawir kfifo at end-of-signal, the behavior
improves quite a bit.

[media] rc: use time unit conversion macros correctly

2011-01-31T14:20:11+00:00

Due to my own stupidity, some of the wrong time unit conversion macros
were being used inside some of the IR drivers I've been working on. Fix
that, and convert over some additional places to also use the macros.

[media] rc: fix sysfs entry for mceusb and streamzap

2010-12-29T10:16:57+00:00

When trying to create persistent device names for mceusb and streamzap
devices, I noticed that their respective drivers are not creating the rc
device as a child of the USB device. Rather it creates it as virtual
device. As a result, udev cannot use the USB device information to
create persistent device names for event and lirc devices associated
with the rc device. Not having persistent device names makes it more

difficult to make use of the devices in userspace as their names can
change.

Forward-ported to media_tree staging/for_v2.6.38 and tested with
both streamzap and mceusb devices:
$ ll /dev/input/by-id/
...
lrwxrwxrwx. 1 root root 9 Nov 17 17:06 usb-Streamzap__Inc._Streamzap_Remote_Control-event-if00 -> ../event6
lrwxrwxrwx. 1 root root 9 Nov 17 17:05 usb-Topseed_Technology_Corp._eHome_Infrared_Transceiver_TS000BzY-event-if00 -> ../event5
Previously, nada.

[media] rc: rename the remaining things to rc_core

2010-12-29T10:16:50+00:00

The Remote Controller subsystem is meant to be used not only by Infra Red
but also for similar types of Remote Controllers. The core is not specific
to Infra Red. As such, rename:
	- ir-core.h to rc-core.h
	- IR_CORE to RC_CORE
	- namespace inside rc-core.c/rc-core.h

To be consistent with the other changes.

No functional change on this patch.

[media] ir-core: make struct rc_dev the primary interface

2010-12-29T10:16:37+00:00

This patch merges the ir_input_dev and ir_dev_props structs into a single
struct called rc_dev. The drivers and various functions in rc-core used
by the drivers are also changed to use rc_dev as the primary interface
when dealing with rc-core.

This means that the input_dev is abstracted away from the drivers which
is necessary if we ever want to support multiple input devs per rc device.

The new API is similar to what the input subsystem uses, i.e:
rc_device_alloc()
rc_device_free()
rc_device_register()
rc_device_unregister()
