Use kmemdup when some other buffer is immediately copied into the allocated region. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression from,to,size,flag; statement S; @@ - to = \(kmalloc\|kzalloc\)(size,flag); + to = kmemdup(from,size,flag); if (to==NULL || ...) S - memcpy(to, from, size); // </smpl> Signed-off-by:

Add a mutex_unlock missing on the error path. In the other functions in the same file the locks and unlocks of this mutex appear to be balanced, so it would seem that the same should hold in this case. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression E1; @@ * mutex_lock(E1,...); <+... when != E1 if (...) { ... when != E1 * return ...; } ...+> * mutex_unlock(E1,...); // </smpl> Signed-off-by:

My previous patch to depend on FONTS was not sufficient since FONTS is boolean. VIDEO_VIVI needs to depend on a tristate so that it won't be enabled as =y when framebuffer is built as modular, so modify it to depend on the same symbols that FONTS depends on, which are FRAMEBUFFER_CONSOLE || STI_CONSOLE. Fixes this build error when VIDEO_VIVI=y and FRAMEBUFFER_CONSOLE=m: vivi.c:(.init.text+0x7205): undefined reference to `find_font' Signed-off-by:

I have pinnacle hardware now. None of this pinnacle-specific crap is at all necessary (in fact, some of it needed to be removed to actually make it work). The only thing unique about this device is that it often transfers inbound data w/a header of 0x90, meaning 16 bytes of IR data following it, so I had to make adjustments for that, and now its working perfectly fine.

The first-gen mceusb device init code, while mostly functional, had a few issues in it. This patch does the following: 1) removes use of magic numbers 2) eliminates mapping of memory from stack 3) makes debug spew translator functional Additionally, this clean-up revealed that we cannot read the proper default tx blaster bitmask from the device, we do actually have to initialize it ourselves, which requires use of a somewhat gross list-based mask inversion check. This patch also removes the entirely unnecessary use of struct ir_input_state. Also supersedes two earlier patches that also touched on first-gen cleanup, but were partially botched. This one actually compiles, works, etc., I swear. ;) Signed-off-by:

Was using input_unregister_device directly, instead of using ir_input_unregister, which tears down a bunch of other things in addition to eventually calling input_unregister_device. Signed-off-by:

This patch moves the state from each raw decoder into the ir_raw_event_ctrl struct. This allows the removal of code like this: spin_lock(&decoder_lock); list_for_each_entry(data, &decoder_list, list) { if (data->ir_dev == ir_dev) break; } spin_unlock(&decoder_lock); return data; which is currently run for each decoder on each event in order to get the client-specific decoding state data. In addition, ir decoding modules and ir driver module load order is now independent. Centralizing the data also allows for a nice code reduction of about 30% per raw decoder as client lists and client registration callbacks are no longer necessary (but still kept around for the benefit of the lirc decoder). Out-of-tree modules can still use a similar trick to what the raw decoders did before this patch until they are merged. Signed-off-by:David Härdeman <david@hardeman.nu> Acked-by:

With this change, it is now possible to do something like: su -c 'echo "none +rc-5 +nec" > /sys/class/rc/rc1/protocols' This prevents the need of multiple opens, one for each protocol change, and makes userspace application easier. Signed-off-by: -
Mauro Carvalho Chehab authored
Writing "none" to /dev/class/rc/rc*/protocols will disable all protocols. This allows an easier setup, from userspace, as userspace applications don't need to disable protocol per protocol, before enabling a different set of protocols. Signed-off-by: -

While rc-5 and rc-6 protocols are generally abreviated as "rc5" and "rc6", previous sysfs nodes uses rc-5 and rc-6 for the Philips protocols. This is consistent with the protocol nomenclature given by the original Philips spec: "Remote control system RC-5" (doc. Nr. 9398 706 23011). Also, rc5 is the name of a widely known cryptography protocol. So, the better is to keep referring to those protocols as "rc-5" and "rc-6". Signed-off-by: -

With the current logic, each raw decoder needs to add a copy of the exact same sysfs code. This is both unnecessary and also means that (re)loading an IR driver after raw decoder modules have been loaded won't work as expected. This patch moves that logic into ir-raw-event and adds a single sysfs file per device. Reading that file returns something like: "rc5 [rc6] nec jvc [sony]" (with enabled protocols in [] brackets) Writing either "+protocol" or "-protocol" to that file will enable or disable the according protocol decoder. An additional benefit is that the disabling of a decoder will be remembered across module removal/insertion so a previously disabled decoder won't suddenly be activated again. The default setting is to enable all decoders. This is also necessary for the next patch which moves even more decoder state into the central raw decoding structs. Signed-off-by:

Instead of generating one printk for every IR read, prints it only when count is different from the last count. While here, as this code is called on every 100ms during the runtime lifetime, do some performance optimization, assuming that, under normal circumstances, it is unlikely that the driver would get a new key/key repeat on every poll.

This patch address an arithmetic error for the case where the only remaining content in the USB packet was the "225Axxxx" start of active video. In cases where that happened to be at the end of the frame, we would inject it into the videobuf (which is incorrect). This caused fields to be intermittently rendered off by two pixels.
