The bt8xx driver only uses the big kernel lock in its dst_ca_ioctl function and never to serialize against other code, so we can trivially replace it with a private mutex. Signed-off-by:

The dvb core only uses the big kernel lock in the open and ioctl functions, which means it can be replaced with a dvb specific mutex. Fortunately, all the ioctl functions go through dvb_usercopy, so we can move the serialization in there. Signed-off-by:

Code in function cx22702_set_tps() can be slightly simplified. Apparently gcc was smart enough to optimize it anyway, but it can't hurt to make the code more readable. Signed-off-by:

The init sequence never changes so it can be marked const. Likewise, cx22702_ops is a template and can thus be made read-only. Signed-off-by:

Calling the same functions in if/else or switch/case branches is inefficient. Refactor the code for a smaller binary and increased readability. Signed-off-by:

This allows the removal of CONFIG_INPUT from saa7134, and helps to create a better Kconfig dependency hierarchy. Signed-off-by: -

The tda8425 initialization function sets up the inputmap for riva boards. After some digging I discovered that this was for the V4L rivatv driver that is found on sourceforge. This driver hasn't been maintained since the last 5 years and will no longer work with the current v4l framework. So we can safely remove this. Signed-off-by:

Currently, they get set up with the pad keytable, which they can't actually use at all. Also add another variant of volume scancodes from another 0xffdc device, and properly set up the 0x9e 0xffdc device as an iMON VFD w/MCE proto IR. Based on data and a prior patch from Anders Eriksson on the lirc list. Signed-off-by:

Lest we get our keycodes wrong... Thus far, in practice, I've not found it to actually matter, but its one of the issues raised in https://bugzilla.kernel.org/show_bug.cgi?id=16351 that wasn't addressed by converting to using native IR keydown/up functions. Signed-off-by:

This is a stab at separating the mouse (and front panel/knob) events out to a separate input device. This is necessary in preparation for the next patch which makes the rc-core input dev opaque to rc drivers. I can't verify the correctness of the patch beyond the fact that it compiles without warnings. The driver has resisted most of my attempts at understanding it properly...for example, the double calls to le64_to_cpu() and be64_to_cpu() which are applied in imon_incoming_packet() and imon_panel_key_lookup() would amount to a bswab64() call, irregardless of the cpu endianness, and I think the code wouldn't have worked on a big-endian machine... - Minor alterations to apply with minimal core IR changes - Use timer for imon keys too, since its entirely possible for the receiver to miss release codes (either by way of another key being pressed while the first is held or by the remote pointing away from the recevier when the key is release. yes, I know, its ugly). - Bump driver version number, since this is a fairly significant change (for the much much better). Tested successfully w/an imon knob receiver. Signed-off-by:

The imon driver currently reimplements its own version of ir_keyup (along with key release timer functionality also already present in the core IR code). A follow-up imon patch will make use of ir_keyup and the IR stack's key release code. Trivial extraction from David Härdeman's pending rc-core merge and device interface abstraction patchset to facilitate merging a patch based on his imon input dev split patch ahead of the larger churn, which is slated for post-2.6.37-rc1 (after Dmitry's large keycode patches are merged in mainline).

The only reason for keeping I2C_HW_SAA7134 is to allow setting a per-device polling interval. Just move this info to the platform data, allowing drivers to change it per device, where needed. Signed-off-by: -

Move the cx88 specific initialization for Hauppauge XVR remotes into cx88-input, removing the need for test it inside ir-kbd-i2c. The reference at cx88 for this symbol, at: drivers/media/video/cx88/cx88-i2c.c: core->i2c_adap.id = I2C_HW_B_CX2388x; drivers/media/video/cx88/cx88-vp3054-i2c.c: vp3054_i2c->adap.id = I2C_HW_B_CX2388x; Can't be removed yet, since lirc-i2c still uses it.

Removed the BKL from usbvision. There was an initialization bug as well where the i2c bus was registered twice. Although when the BKL was present no oops was generated, I did run into other i2c problems. Now that I protect against duplicate i2c registration that bug is now gone as well. But trying to disconnect the USB cable while someone is still using the device still leads to a crash. Signed-off-by:

The include/media/v4l2-i2c-drv.h header was used to be able to compile drivers in the v4l-dvb hg repository for legacy kernels (mainly pre-2.6.26) without creating an #ifdef mess. The hg repository dropped support for kernels < 2.6.26 so we can remove this header. All i2c drivers that used it have now been converted to use proper i2c code. The header was a hack, but it did its job well. So I would call this an honorable removal. :-) Signed-off-by:
