2016-11-16mfd: stmpe: Fix RESET regression on STMPE2401Linus Walleij
Since commit c4dd1ba355aae2bc3d1213da6c66c53e3c31e028 ("mfd: stmpe: Add reset support for all STMPE variant") we're resetting the STMPE expanders before use. This caused a regression on the STMP2401 on the Nomadik NHK8815: stmpe-i2c 0-0043: stmpe2401 detected, chip id: 0x101 nmk-i2c 101f8000.i2c0: write to slave 0x43 timed out nmk-i2c 101f8000.i2c0: no ack received after address transmission stmpe-i2c 0-0044: stmpe2401 detected, chip id: 0x101 nmk-i2c 101f8000.i2c0: write to slave 0x44 timed out nmk-i2c 101f8000.i2c0: no ack received after address transmission It turns out that we start to poll for the reset bit to go low again too quickly: the STMPE2401 is not yet online and ready to be asked for the status of the RESET bit. By introducing a 10ms delay before starting to hammer the register for information, we get back to normal: stmpe-i2c 0-0043: stmpe2401 detected, chip id: 0x101 stmpe-i2c 0-0044: stmpe2401 detected, chip id: 0x101 Cc: stable@vger.kernel.org Cc: Amelie Delaunay <amelie.delaunay@st.com> Fixes: c4dd1ba355aa ("mfd: stmpe: Add reset support for all STMPE variant") Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Acked-by: Patrice Chotard <patrice.chotard@st.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

Due to the resetting of device, system cannot enter S3/S0ix states when no_console_suspend flag is enabled. The system and serial console both hang. The resetting of device is not needed while going to suspend. Hence remove this code.

There are a few issues on Intel Kaby Lake PCH-H properties added by commit a6a576b78e09 ("mfd: lpss: Add Intel Kaby Lake PCH-H PCI IDs"): - Input clock of I2C controller on Intel Kaby Lake PCH-H is 120 MHz not 133 MHz. This was probably copy-paste error from Intel Broxton I2C properties. - There is no default I2C SDA hold time specified which is used when ACPI doesn't provide it. I got information from Windows driver team that Kaby Lake PCH-H can use the same configuration than Intel Sunrisepoint PCH. - Common HS-UART properties are not used. Fix these by reusing the Sunrisepoint properties on Kaby Lake PCH-H.

2016-11-16drm/i915: Assume non-DP++ port if dvo_port is HDMI and there's no AUX ch ↵Ville Syrjälä
specified in the VBT My heuristic for detecting type 1 DVI DP++ adaptors based on the VBT port information apparently didn't survive the reality of buggy VBTs. In this particular case we have a machine with a natice HDMI port, but the VBT tells us it's a DP++ port based on its capabilities. The dvo_port information in VBT does claim that we're dealing with a HDMI port though, but we have other machines which do the same even when they actually have DP++ ports. So that piece of information alone isn't sufficient to tell the two apart. After staring at a bunch of VBTs from various machines, I have to conclude that the only other semi-reliable clue we can use is the presence of the AUX channel in the VBT. On this particular machine AUX channel is specified as zero, whereas on some of the other machines which listed the DP++ port as HDMI have a non-zero AUX channel. I've also seen VBTs which have dvo_port a DP but have a zero AUX channel. I believe those we need to treat as DP ports, so we'll limit the AUX channel check to just the cases where dvo_port is HDMI. If we encounter any more serious failures with this heuristic I think we'll have to have to throw it out entirely. But that could mean that there is a risk of type 1 DVI dongle users getting greeted by a black screen, so I'd rather not go there unless absolutely necessary. v2: Remove the duplicate PORT_A check (Daniel) Fix some typos in the commit message Cc: Daniel Otero <daniel.otero@outlook.com> Cc: stable@vger.kernel.org Tested-by: Daniel Otero <daniel.otero@outlook.com> Fixes: d61992565bd3 ("drm/i915: Determine DP++ type 1 DVI adaptor presence based on VBT") Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97994 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1478884464-14251-1-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> (cherry picked from commit 7a17995a3dc8613f778a9e2fd20e870f17789544) Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2016-11-15IB/hfi1: Fix a potential memory leak in hfi1_create_ctxts()Jianxin Xiong
In the function hfi1_create_ctxts the array "dd->rcd" is allocated and then populated with allocated resources in a loop. Previously, if error happened during the loop, only resource allocated in the current iteration would be freed. The array itself would then be freed, leaving the resources that were allocated in previous iterations and referenced by the array elements in limbo. This patch makes sure all allocated resources are freed before freeing the array "dd->rcd". Also the resource allocation now takes account of the numa node the device is attached to.

2016-11-15IB/hfi1: Fix an Oops on pci device force removeTadeusz Struk
This patch fixes an Oops on device unbind, when the device is used by a PSM user process. PSM processes access device resources which are freed on device removal. Similar protection exists in uverbs in ib_core for Verbs clients, but PSM doesn't use ib_uverbs hence a separate protection is required for PSM clients.
