Applied to drm-misc-fixes, thanks!

[2/6] drm/bridge: aux-hpd: separate allocation and registration
      commit: e5ca263508f7e9d2cf711edf3258d11ca087885c
[3/6] soc: qcom: pmic_glink_altmode: fix drm bridge use-after-free
      commit: b979f2d50a099f3402418d7ff5f26c3952fb08bb
[4/6] soc: qcom: pmic_glink: Fix boot when QRTR=m
      commit: f79ee78767ca60e7a2c89eacd2dbdf237d97e838

Note, PHY patches (5,6) do not have dependency on the drm patch, so they can go
through the phy/fixes tree.

Best regards,
