2016-07-18cdc-acm: use the common parserOliver Neukum
This introduces the common parser for extra CDC headers now that it no longer depends on usbnet. Signed-off-by: Oliver Neukum <ONeukum@suse.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2016-07-18perf jit: Remove some no-op error handlingDan Carpenter
The 'info.e_machine' struct member is an uint16_t so 'm' is never less than zero. It looks like this was maybe left over code from earlier versions so I've just removed it.

2016-07-18ASoC: rockchip: correct the spdif clkChris Zhong
The spdif mclk should be 128 times of sample rate, and there is a internal divider, the real rate of spdif mclk is mclk / (div + 1). Hence, the original driver always get the good frequency for 48000/96000/44100/192000. But for 32000, the mclk is incorrect, it should be 32000*128, but get 48000*128. Do not use the internal divider here, just set all mclk to 128 * sample rate directly. Signed-off-by: Chris Zhong <zyw@rock-chips.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2016-07-18[media] doc-rst: move bttv documentation to bttv.rst fileMauro Carvalho Chehab
There were several files under Documentation/video4linux/bttv. Instead of simply copying them to the rst folder, I opted to merge into a single document and adjust the headers to adjust the section levels and fix the cards tables. There are two exceptions on the merge: - The Tuners were renamed as a separate document, as they describe a separate driver; - I removed the PROBLEMS section. It describes problems with the very first generation of 3D boards (Mistique/S3). It sounds very unlikely that someone would still need to install a bttv board on such hardware. Also, it is not very well written, IMHO. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

eDP should be treated as connected even if doesn't have an EDID. In that case we'll use the timings from the VBT. That used to be the case until commit f21a21983ef1 ("drm/i915: Splitting intel_dp_detect") broke things by considering even eDP disconnected if we fail to get an EDID for it.

2016-07-18crypto: scatterwalk - Remove unnecessary advance in scatterwalk_pagedoneHerbert Xu
The offset advance in scatterwalk_pagedone not only is unnecessary, but it was also buggy when it was needed by scatterwalk_copychunks. As the latter has long ago been fixed to call scatterwalk_advance directly, we can remove this unnecessary offset adjustment. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2016-07-18crypto: scatterwalk - Fix test in scatterwalk_doneHerbert Xu
When there is more data to be processed, the current test in scatterwalk_done may prevent us from calling pagedone even when we should. In particular, if we're on an SG entry spanning multiple pages where the last page is not a full page, we will incorrectly skip calling pagedone on the second last page.

This patch removes the old crypto_grab_skcipher helper and replaces it with crypto_grab_skcipher2.
