2011-01-19[media] et61x251: remove wrongly claimed usb idsHans de Goede
The et61x251 driver claims a whole list of usb id's, but it only has one sensor "module" which does sensor detection based on usb id and that only supports devices with the 102c:6251 usb id. Remove the usb-ids for other devices as for those the driver will fail with an unable to determine sensor type message anyways.

2011-01-19[media] gspca_main: wake wq on streamoffHans de Goede
We check for not streaming as a condition to abort waiting in dqbuf, so when another thread does a streamoff we should wake the wq. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Jean-Francois Moine <moinejf@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-01-19[media] gspca_main: Allow switching from read to mmap / userptr modeHans de Goede
Some applications (xawtv, qv4l2) mix read and mmap calls. Allow switching from read mode back to mmap mode (by doing a reqbufs). Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Jean-Francois Moine <moinejf@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-01-19[media] gspca_main: Simplify read mode memory type checksHans de Goede
gspca_dev->memory == GSPCA_MEMORY_NO implies gspca_dev->nframes == 0, so there is no need to check for both in dev_poll. The check in dev_read also is more complex then needed, as dqbuf which dev_read calls already does all necessary checks. Moreover dqbuf is holding the proper locks while checking where as dev_read itself is not.

2011-01-19[media] gspca_main: Set memory type to GSPCA_MEMORY_NO on buffer releaseHans de Goede
Before this patch we were not setting the memory type to GSPCA_MEMORY_NO when the buffers were released by the app doing a reqbufs 0. Nor would the memory type be set to GSPCA_MEMORY_NO on device close, as capture_file already is NULL on device close because of the reqbufs 0. This caused the following problem: -app1 does reqbufs USERPTR for 4 buffers -app1 does reqbufs USERPTR for 0 buffers -app2 tries to do reqbufs MMAP for 4 buffers fails because gspca_dev->memory still is USERPTR Fixing this also allows an app to switch memory type's by unrequesting the buffers and re-requesting them of a different type. This patch also moves the setting of gspca_dev->frsz and gscpa_dev->memory to after alloc_frame succeeding, so that they are not changed when allocating fails.

2011-01-19[media] gspca_main: Update buffer flags even when user_copy failsHans de Goede
Before this patch dqbuf errors out on a failing user_copy (with user pointers) before updating the buffer flags, causing a successsfully dequeued buffer to still have the DONE flag, which means that it could no longer be re-queueud (assuming the app somehow survives the segfault).

2011-01-19[media] gspca_main: Locking fixes 2Hans de Goede
Before this patch vidioc_dqbuf is using its own read_lock, where as other queue related functions use queue_lock. This means that dqbuf is accessing several variables in a racy manor. The most important one being fr_o, which may be changed from underneath dqbuf by vidioc_reqbufs or vidioc_streamoff. Other variables which it accesses unprotected are gspca_dev->memory, gspca_dev->streaming and gspca_dev->capt_file. This patch fixes this by changing vidioc_dqbuf to also use the queue_lock.

2011-01-19[media] gspca_main: Locking fixes 1Hans de Goede
The gspca_dev->streaming boolean is protected against multiple access through gspca_dev->queue_lock everywhere except for 2 places. This patch fixes this by bringing it under the lock in vidioc_streamoff. And by removing the check for gspca_dev->streaming in gspca_disconnect, the destroy_urbs call may be called multiple times (and is protected by the usb_lock) and calling wake_up_interruptible can also always be done safely.

2011-01-19[media] tda9875: remove duplicate driverHans Verkuil
In commit 411674fd189abe5910ea4caf08b7eac5c4a4d967 the tda9875 support was added to tvaudio. This means that tda9875 is no longer used since mid-2009. If there are out-of-tree users of this driver, then they can switch to tvaudio instead. The original commit message read as follows: This change allows bttv to use tvaudio for this device. Since this device has the same i2c address as the tda9874 we need to support both in the same tvaudio driver. This makes it possible for tvaudio to detect which chip is used. Originally the tda9875 was only available in the dedicated tda9875 driver, but that makes life very hard for bttv since loading tvaudio might misdetect a tda9875 as a tda9874. So there were good reasons for moving the tda9875 code into tvaudio. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-01-18MIPS: jump label: Add MIPS support.David Daney
In order not to be left behind, we add jump label support for MIPS. Tested on 64-bit big endian (Octeon), and 32-bit little endian (malta/qemu).

2011-01-18MIPS: Use WARN() in uasm for better diagnostics.David Daney
On the off chance that uasm ever warns about overflow, there is no way to know what the offending instruction is. Change the printks to WARNs, so we can get a nice stack trace. It has the added benefit of being much more noticeable than the short single line warning message, so is less likely to be ignored.

2011-01-18MIPS: Optimize TLB handlers for Octeon CPUsDavid Daney
Octeon can use scratch registers in the TLB handlers. Octeon II can use LDX instructions. Signed-off-by: David Daney <ddaney@caviumnetworks.com> To: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/1904/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2011-01-18MIPS: Add LDX and LWX instructions to uasm.David Daney
Needed by Octeon II optimized TLB handlers. Signed-off-by: David Daney <ddaney@caviumnetworks.com> To: linux-mips@linux-mips.org Pachwork: https://patchwork.linux-mips.org/patch/1903/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2011-01-18MIPS: Use BBIT instructions in TLB handlersDavid Daney
If the CPU supports BBIT0 and BBIT1, use them in TLB handlers as they are more efficient than an AND followed by an branch and then restoring the clobbered register.
