media: dvb: warning about dvb frequency limits produces too much noise

2019-06-19T06:00:03Z

commit eb96e57b913ff668b8b804178cdc509f9b3d4472 upstream. This can be a debug message. Favour dev_dbg() over dprintk() as this is already used much more than dprintk(). dvb_frontend: dvb_frontend_get_frequency_limits: frequency interval: tuner: 45000000...860000000, frontend: 44250000...867250000 Fixes: 00ecd6bc7128 ("media: dvb_frontend: add debug message for frequency intervals") Cc: # 5.0 Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Greg Kroah-Hartman

Use codespell to fix lots of typos over frontends. Manually verified to avoid false-positives. Signed-off-by: Mauro Carvalho Chehab

media: dvb-core: fix epoll() by calling poll_wait first

2019-02-18T19:48:37Z

The epoll function expects that whenever the poll file op is called, the poll_wait function is also called. That didn't always happen in dvb_demux_poll(), dvb_dvr_poll() and dvb_ca_en50221_io_poll(). Fix this, otherwise epoll() can timeout when it shouldn't. Signed-off-by: Hans Verkuil Reviewed-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: dvb_frontend: add debug message for frequency intervals

2018-11-23T16:59:45Z

As we did an internal change inside the subsystem to always represent min/max frequencies in Hz, add a debug message, as this would help to discover bugs on drivers, if any. Signed-off-by: Mauro Carvalho Chehab

media: dvb_frontend: don't print function names twice

2018-11-23T16:59:22Z

The dvb_frontend dprintk() macro already prints __func__. So, we don't need to add it again at the printed message. Signed-off-by: Mauro Carvalho Chehab

Pull new experimental media request API from Mauro Carvalho Chehab: "A new media request API This API is needed to support device drivers that can dynamically change their parameters for each new frame. The latest versions of Google camera and codec HAL depends on such feature. At this stage, it supports only stateless codecs. It has been discussed for a long time (at least over the last 3-4 years), and we finally reached to something that seem to work. This series contain both the API and core changes required to support it and a new m2m decoder driver (cedrus). As the current API is still experimental, the only real driver using it (cedrus) was added at staging[1]. We intend to keep it there for a while, in order to test the API. Only when we're sure that this API works for other cases (like encoders), we'll move this driver out of staging and set the API into a stone. [1] We added support for the vivid virtual driver (used only for testing) to it too, as it makes easier to test the API for the ones that don't have the cedrus hardware" * tag 'media/v4.20-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (53 commits) media: dt-bindings: Document the Rockchip VPU bindings media: platform: Add Cedrus VPU decoder driver media: dt-bindings: media: Document bindings for the Cedrus VPU driver media: v4l: Add definition for the Sunxi tiled NV12 format media: v4l: Add definitions for MPEG-2 slice format and metadata media: videobuf2-core: Rework and rename helper for request buffer count media: v4l2-ctrls.c: initialize an error return code with zero media: v4l2-compat-ioctl32.c: add missing documentation for a field media: media-request: update documentation media: media-request: EPERM -> EACCES/EBUSY media: v4l2-ctrls: improve media_request_(un)lock_for_update media: v4l2-ctrls: use media_request_(un)lock_for_access media: media-request: add media_request_(un)lock_for_access media: vb2: set reqbufs/create_bufs capabilities media: videodev2.h: add new capabilities for buffer types media: buffer.rst: only set V4L2_BUF_FLAG_REQUEST_FD for QBUF media: v4l2-ctrls: return -EACCES if request wasn't completed media: media-request: return -EINVAL for invalid request_fds media: vivid: add request support media: vivid: add mc ...

media: replace strcpy() by strscpy()

The strcpy() function is being deprecated upstream. Replace it by the safer strscpy(). Signed-off-by: Mauro Carvalho Chehab Reviewed-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: use strscpy() instead of strlcpy()

The implementation of strscpy() is more robust and safer. That's now the recommended way to copy NUL terminated strings. Signed-off-by: Mauro Carvalho Chehab Reviewed-by: Kees Cook Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
