The ->vidioc_(s|g|try|enum)_fmt_vid_cap() methods are only called on VIDEO_CAPTURE buffers. Thus, there is no need to check or set the 'type' field since it must already be set to VIDEO_CAPTURE. Signed-off-by:

The v4l2 core code in v4l2_ioctl will zero out the structure the driver is supposed to fill in for read-only ioctls. For read/write ioctls, all the fields which aren't supplied from userspace will be zeroed out. Zeroing code is removed from enum_input, g_tuner, g_frequency, querycap, enum_fmt_vid_cap, g_fmt_vid_cap, and try_fmt_vid_cap. The ->vidioc_(s|g|try|enum)_fmt_vid_cap() methods are only called on VIDEO_CAPTURE buffers. Thus, there is no need to check or set the buffer's 'type' field since it must already be set to VIDEO_CAPTURE. There also appeared to be a copy and paste error in vidioc_try_fmt_vid_cap() that would set f->fmt.pix.sizeimage to zero. Note that the s_fmt_vid_cap method doesn't appear to actually do anything. Whatever parameters were requested are just silently ignored. Was this intentional? Who knows, as the commit log entry for the driver just says, "Add generic cx23417 hardware encoder support." There are no docs. A comment like "this driver totally ignores the v4l2 spec w.r.t. VIDIOC_S_FMT because ..." would have gone a long way. Cc: Steven Toth <stoth@hauppauge.com> Signed-off-by:

The v4l2-ioctl core only allows buffer types for which the corresponding ->vidioc_try_fmt_xxx() methods are defined to be used with vidioc_(q|dq|query)bufs() and vidioc_reqbufs(). This driver only defines ->vidioc_try_fmt_vid_cap() so only VIDEO_CAPTURE buffers are allowed to be used with cafe_vidioc_reqbufs(), cafe_vidioc_querybuf(), cafe_vidioc_qbuf(), and cafe_vidioc_dqbuf(). The ->vidioc_(s|g|try|enum)_fmt_vid_cap() methods are only called on VIDEO_CAPTURE buffers. Thus, there is no need to check or set the buffer's 'type' field since it must already be set to VIDEO_CAPTURE. So the check in cafe_vidioc_enum_fmt_vid_cap() can be removed. The 'index' field of v4l2_buffer is unsigned so the checks for it being less than zero can be removed too. Signed-off-by:

The v4l2-ioctl core only allows buffer types for which the corresponding ->vidioc_try_fmt_xxx() methods are defined to be used in vidioc_(g|s)_parm, vidioc_(q|dq|query)buf, and vidioc_reqbufs. Remove buffer type checking from vino_g_parm(), vino_s_parm(), vino_reqbufs(), vino_querybuf(), vino_qbuf(), and vino_dqbuf(). This reduced the indent level of the code so a few lines can be wrapped better. Also fixed the C++ type comments. The v4l2-ioctl core also provides structs that have been pre-zeroed for all fields that driver is supposed to fill in, so remove zeroing code from vino_enum_fmt_vid_cap(). Also, the format index is unsigned so it's not necessary to check if it's less than zero. Signed-off-by:

The v4l2-ioctl core checks the buffer type now by only allowing buffer types for which the corresponding ->vidioc_try_fmt_xxx() methods are defined. This driver only defines ->vidioc_try_fmt_vid_cap() so only VIDEO_CAPTURE buffers are allowed to be used with vidioc_g_parm. Also, ->vidioc_enum_fmt_vid_cap() is only called for VIDEO_CAPTURE buffers. There is no need to set the buffer type since it must already be the correct value. The struct which ->vidioc_querycap() is supposed to fill in is already zeroed so it's not necessary to call memset on it. Cc: Jean-Francois Moine <moinejf@free.fr> Signed-off-by:

The driver was only allowing VIDEO_CAPTURE buffers for g_parm, but since the driver defines ->vidioc_try_fmt_vid_overlay() and ->vidioc_try_fmt_vbi_cap() it will now allow VIDEO_OVERLAY and VBI_CAPTURE buffers as well. This should be fine as the driver only fills in the frame rate field, which is just as valid for video overlay and vbi capture as it is for video capture. Signed-off-by:

Return EINVAL if VIDIOC_S/G_PARM is called for a buffer type that the driver doesn't define a ->vidioc_try_fmt_XXX() method for. Several other ioctls, like QUERYBUF, QBUF, and DQBUF, etc. do this too. It saves each driver from having to check if the buffer type is one that it supports. Signed-off-by:

Drivers that don't set "config" directly in the set_type function will end up with an invalid configuration value. Check that the value is sane, otherwise initialize to 0.

The ioremap one was reported in October 2007 (Bug 9146), the kmalloc one was blindingly obvious while looking at the ioremap one The bug suggests some other configuration for lots of I/O memory (32MB per device is ioremapped) but I'll leave that to the real maintainers Signed-off-by:

Separate tuning table for DVB-C solves tuning problem at 388MHz TechnoTrend C-1501 DVB-C card does not lock on 388MHz. I assume that existing frequency table is valid for DVB-T. This is suggested by the name of the table: tda827xa_dvbt. Added a table for DVB-C with the name tda827xa_dvbc. Added runtime selection of the DVB-C table when the tuner is type FE_QAM. This should leave the behaviour of this driver with with DVB_T tuners unchanged. This modification is in file tda827x.c The tda827x.c gives the following warning message when debug=1: tda827x: tda827x_config not defined, cannot set LNA gain! Solved this by adding a tda827x_config struct in budget-ci.c. Signed-off-by:
