2020-09-10media: rcar_drif: Fix fwnode reference leak when parsing DTLaurent Pinchart
The fwnode reference corresponding to the endpoint is leaked in an error path of the rcar_drif_parse_subdevs() function. Fix it, and reorganize fwnode reference handling in the function to release references early, simplifying error paths.

2020-09-10media: v4l2-async: Document asd allocation requirementsLaurent Pinchart
The v4l2_async_notifier_add_subdev() function requires the asd pointer it receives to be allocated dynamically, but doesn't explicitly say so. Only one driver out of 13 get its right (atmel-sama5d2-isc.c, but with memory leaks in the error paths), clearly showing we have an issue. Update the v4l2_async_notifier_add_subdev() documentation to clearly state the allocation requirement. Whether this will be enough to avoid new offending code isn't certain, but it's a good first step nonetheless.

2020-09-10media: i2c: ov5640: Enable data pins on poweron for DVP modeLad Prabhakar
During testing this sensor on iW-RainboW-G21D-Qseven platform in 8-bit DVP mode with rcar-vin bridge noticed the capture worked fine for the first run (with yavta), but for subsequent runs the bridge driver waited for the frame to be captured. Debugging further noticed the data lines were enabled/disabled in stream on/off callback and dumping the register contents 0x3017/0x3018 in ov5640_set_stream_dvp() reported the correct values, but yet frame capturing failed. To get around this issue data lines are enabled in s_power callback.

2020-09-10media: uvcvideo: Ensure all probed info is returned to v4l2Adam Goode
bFrameIndex and bFormatIndex can be negotiated by the camera during probing, resulting in the camera choosing a different format than expected. v4l2 can already accommodate such changes, but the code was not updating the proper fields. Without such a change, v4l2 would potentially interpret the payload incorrectly, causing corrupted output. This was happening on the Elgato HD60 S+, which currently always renegotiates to format 1. As an aside, the Elgato firmware is buggy and should not be renegotating, but it is still a valid thing for the camera to do. Both macOS and Windows will properly probe and read uncorrupted images from this camera. With this change, both qv4l2 and chromium can now read uncorrupted video from the Elgato HD60 S+.

UBSAN reports a shift-out-of-bounds warning in uvc_get_le_value(). The report is correct, but the issue should be harmless as the computed value isn't used when the shift is negative. This may however cause incorrect behaviour if a negative shift could generate adverse side effects (such as a trap on some architectures for instance). Regardless of whether that may happen or not, silence the warning as a full WARN backtrace isn't nice.

2020-09-10media: uvcvideo: Fix uvc_ctrl_fixup_xu_info() not having any effectHans de Goede
uvc_ctrl_add_info() calls uvc_ctrl_get_flags() which will override the fixed-up flags set by uvc_ctrl_fixup_xu_info(). uvc_ctrl_init_xu_ctrl() already calls uvc_ctrl_get_flags() before calling uvc_ctrl_add_info(), so the uvc_ctrl_get_flags() call in uvc_ctrl_add_info() is not necessary for xu ctrls. This commit moves the uvc_ctrl_get_flags() call for normal controls from uvc_ctrl_add_info() to uvc_ctrl_init_ctrl(), so that we no longer call uvc_ctrl_get_flags() twice for xu controls and so that we no longer override the fixed-up flags set by uvc_ctrl_fixup_xu_info(). This fixes the xu motor controls not working properly on a Logitech 046d:08cc, and presumably also on the other Logitech models which have a quirk for this in the uvc_ctrl_fixup_xu_info() function.

2020-09-10media: cec-adap.c: don't use flush_scheduled_work()Hans Verkuil
For some inexplicable reason I decided to call flush_scheduled_work() instead of cancel_delayed_work_sync(). The problem with that is that flush_scheduled_work() waits for *all* queued scheduled work to be completed instead of just the work itself. This can cause a deadlock if a CEC driver also schedules work that takes the same lock. See the comments for flush_scheduled_work() in linux/workqueue.h. This is exactly what has been observed a few times. This patch simply replaces flush_scheduled_work() by cancel_delayed_work_sync().

The for loop in i40e_set_vsi_promisc() reports errors via dev_err() but does not propagate the error up the call chain. Instead it continues the loop and potentially overwrites the reported error value. This results in the error being recorded in the log buffer, but the caller might never know anything went the wrong way. To avoid this situation i40e_set_vsi_promisc() needs to temporarily store the error after reporting it. This is still not optimal as multiple different errors may occur, so store the first error and hope that's the main issue.

2020-09-09i40e: fix return of uninitialized aq_ret in i40e_set_vsi_promiscStefan Assmann
drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c: In function ‘i40e_set_vsi_promisc’: drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c:1176:14: error: ‘aq_ret’ may be used uninitialized in this function [-Werror=maybe-uninitialized] i40e_status aq_ret; In case the code inside the if statement and the for loop does not get executed aq_ret will be uninitialized when the variable gets returned at the end of the function. Avoid this by changing num_vlans from int to u16, so aq_ret always gets set. Making this change in additional places as num_vlans should never be negative.
