As warned by smatch: drivers/media/dvb-frontends/lgdt3306a.c:1354 log10_x1000() error: buffer overflow 'valx_x10' 14 <= 14 drivers/media/dvb-frontends/lgdt3306a.c:1355 log10_x1000() error: buffer overflow 'log10x_x1000' 14 <= 14 There's a potential of returning a value out of the buffer. Fix it. While here, remove the ugly braced block. Signed-off-by:Mauro Carvalho Chehab <mchehab@osg.samsung.com>

While this is not a mandatory rule at the CodingStyle, we prefer hexadecimal values in lowercase. Currently, there's a mix of lowercase and uppercase ons at lgdt3306a. So, convert all to lowercase with this small script: perl -ne 'if (m,0x([\dA-F]+),) { $o=$1; $n=lc $1; s,0x($o),0x$n, } print $_' Signed-off-by: -

The documentation of the xvYCC601 Y'CbCr encoding was part of the SMPTE 170M (SDTV) colorspace, but it should have been part of the Rec. 709 (HDTV) colorspace as per the xvYCC standard. This change only affects the documentation and not any code. Signed-off-by:

The handling of VIDIOC_G/S_PRIORITY is now entirely done by the V4L2 core, so we can drop the g/s_priority ioctl ops. We do have to make sure though that when S_PRIORITY is called we check that the driver used struct v4l2_fh. This check can be removed once all drivers are converted to that structure. Signed-off-by:

Hans Verkuil authored
By using struct v4l2_fh both the prio handling and the linked list implementation in pvrusb2 can be removed since both are now done in the v4l2 core if you use struct v4l2_fh. Signed-off-by:

To keep V4L2 drivers that did not yet convert to unlocked_ioctl happy, the v4l2 core had a .ioctl file operation that took a V4L2 lock. The last drivers are now converted to unlocked_ioctl, so all this old code can now be removed. Signed-off-by:

Hans Verkuil authored
Switch this driver over to the V4L2 core locking mechanism in preparation for switching to unlocked_ioctl. Suggested by Laurent Pinchart. This patch introduces a new mutex at the struct uvc_video level and drops the old mutex at the queue level. The new lock is now used for all ioctl locking and in the release file operation (the driver always has to take care of locking in file operations, the core only serializes ioctls). Note that the mmap and get_unmapped_area file operations no longer take a lock. Commit f035eb4e fixed a AB-BA deadlock by moving all the locking down into vb2, so the mmap and get_unmapped_area file operations should no longer do any locking before calling into vb2.

FM (frequency modulated) signal for SDR is generated by varying the phase, where phase variation is proportional to input signal. It is seen that, the larger phase increments leads to discontinuities in the signal recovered after demodulation. Reducing the extent of phase variation with respect to input signal, equivalent to reducing the modulation index. Tested using FM receiver flow graph in gnuradio-companion.

The common implementation for sin/cos in include/linux/fixp-arith.h has been improved recently to provide higher precision. Replacing native implementation of sin/cos in vivid sdr with common implementation. This serves two purposes: 1. Improved accuracy: the native implementation based on the Taylor series is more prone to rounding errors. 2. Reuse of common function: this is better compared to maintaining native versions for each driver.

The cos table used at fixp-arith.h has only 8 bits of precision. That causes problems if it is reused on other drivers. As some media drivers require a higher precision sin/cos implementation, replace the current implementation by one that will provide 32 bits precision. The values generated by the new implementation matches the 32 bit precision of glibc's sin for an angle measured in integer degrees. It also provides support for fractional angles via linear interpolation. On experimental calculus, when used a table with a 0.001 degree angle, the maximum error for sin is 0.000038, which is likely good enough for practical purposes. There are some logic there that seems to be specific to the usage inside ff-memless.c. Move those logic to there, as they're not needed elsewhere.
