2017-11-29drm/atomic: make drm_atomic_helper_wait_for_vblanks more agressiveLucas Stach
drm_atomic_helper_setup_commit expects that flipping of previous commits has happened when it is called to set up a new commit. This can be violated by commits where userspace doesn't get a flip completion event to synchronize against i.e. legacy modesets and property changes. The expectation is that those are done by blocking commits, which wait for completion. Most drivers call drm_atomic_helper_wait_for_vblanks in the commit_tail to ensure completion, but the wait for next vblank might not actually happen if the commit didn't change any planes. Make the wait more agressive by also waiting if no planes changed. This is the minimal regression fix for the 4.15 kernel series. Long term drivers should switch away from drm_atomic_helper_wait_for_vblanks and use drm_atomic_helper_wait_for_flip_done instead.

2017-11-28drm/amd/display: Do DC mode-change check when adding CRTCsLeo (Sunpeng) Li
Within atomic check, dm_update_crtcs_state is called twice. First to remove from the dc_state, and subsequently to add to it. In both calls, a secondary mode-change check is done using dc-level states. We shouldn't be doing this while removing, since a new dc_stream_state has not been created to do the necessary comparison. Because of this, the mode_changed flag within the DRM state can be mistakenly set to false. Doing so only when adding prevents this. We are also guaranteed that a call to add will come after remove, or else the atomic check fails (and a commit will not happen).

2017-11-28bnxt_en: Fix an error handling path in 'bnxt_get_module_eeprom()'Christophe JAILLET
Error code returned by 'bnxt_read_sfp_module_eeprom_info()' is handled a few lines above when reading the A0 portion of the EEPROM. The same should be done when reading the A2 portion of the EEPROM. In order to correctly propagate an error, update 'rc' in this 2nd call as well, otherwise 0 (success) is returned.

2017-11-28net: phy: marvell10g: fix the PHY id maskAntoine Tenart
The Marvell 10G PHY driver supports different hardware revisions, which have their bits 3..0 differing. To get the correct revision number these bits should be ignored. This patch fixes this by using the already defined MARVELL_PHY_ID_MASK (0xfffffff0) instead of the custom 0xffffffff mask.
