Use refcount_t to manage the refcount to the memory type specific buffer videobuf2 buffer implementations. refcount_t is better suitable for the purpose than atomic_t. Signed-off-by:

The VIDIOC_G_EDID implementation in vivid didn't take edid->start_block into account when copying the EDID data. Make sure that the internal EDID is updated with the correct CEC physical address. Currently the returned EDID is updated, but that will only work well if edid->start_block is 0. Signed-off-by:

Add a helper function to get driver private data from CEC adapter. This helps the readability a little bit and allows to change the 'priv' field name to something else without needing to touch all drivers. Signed-off-by:

The symptom is continuous log "mtk-jpeg 18004000.jpegdec: Context is NULL" in kernel log. It is because the error handling in irq doesn't clear interrupt. The calling flow like as below when issue happen mtk_jpeg_device_run() mtk_jpeg_job_abort() v4l2_m2m_job_finish() -> m2m_dev->curr_ctx = NULL; mtk_jpeg_dec_irq() v4l2_m2m_get_curr_priv() -> m2m_dev->curr_ctx == NULL -> return NULL log "Context is NULL" There is race condition between job_abort() and irq. In order to simplify code, don't want to add extra flag to maintain state, empty job_abort() and clear interrupt before v4l2_m2m_get_curr_priv() in irq.

Make sure to check the number of endpoints to avoid accessing memory beyond the endpoint array should a device lack the expected endpoints. Note that, as far as I can tell, the gspca framework has already made sure there is at least one endpoint in the current alternate setting so there should be no risk for a NULL-pointer dereference here.

This driver was merged in 2010 and never had the necessary work done to promote it out of staging (port to rc-core), so remove it. I have not managed to track down the hardware. If anyone has the hardware and would like a driver for it, please contact me and hopefully we can work together to write a new driver. Signed-off-by:

Support for these sir ports is not compiled in by default, it has to be enabled by manually defining LIRC_TEKRAM, LIRC_SIR_ACTISYS_ACT200L or LIRC_SIR_ACTISYS_ACT220L somewhere. This cannot be done from Kconfig at all so remove them from the driver. Signed-off-by:

Pull parisc fixes from Helge Deller: "Al Viro reported that - in case of read faults - our copy_from_user() implementation may claim to have copied more bytes than it actually did. In order to fix this bug and because of the way how gcc optimizes register usage for inline assembly in C code, we had to replace our pa_memcpy() function with a pure assembler implementation. While fixing the memcpy bug we noticed some other issues with our get_user() and put_user() functions, e.g. nested faults may return wrong data. This is now fixed by a common fixup handler for get_user/put_user in the exception handler which additionally makes generated code smaller and faster. The third patch is a trivial one-line fix for a patch which went in during 4.11-rc and which avoids stalled CPU warnings after power shutdown (for parisc machines which can't plug power off themselves). Due to the rewrite of pa_memcpy() into assembly this patch got bigger than what I wanted to have sent at this stage. Those patches have been running in production during the last few days on our debian build servers without any further issues" * 'parisc-4.11-3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Avoid stalled CPU warnings after system shutdown parisc: Clean up fixup routines for get_user()/put_user() parisc: Fix access fault handling in pa_memcpy()
