Subject: [media] pixfmt.rst: drop V4L2_YCBCR_ENC_SYCC from the documentation
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=dda3aeaa16434482c2aec03c54262dd2bc9c357b;p=openwrt%2Fstaging%2Fblogic.git

[media] pixfmt.rst: drop V4L2_YCBCR_ENC_SYCC from the documentation

The V4L2_YCBCR_ENC_SYCC encoding is identical to V4L2_YCBCR_ENC_601.
Remove V4L2_YCBCR_ENC_SYCC from the documentation since it should not
be used.
