f0ae8685b2 phy: HiSilicon: Fix copy and paste bug in error handling
This should check ">pmctrl" instead of "->sysctrl".  This bug could
potentially lead to a crash if we dereference the error pointer.

  Included are:

     acked by the dma_buf maintainers

   - iio driver update (going through this tree not staging as they
     really do not belong going through that tree anymore)

   - counter driver updates

   - hwmon driver updates that the counter drivers needed, acked by the
     hwmon maintainer

   - xillybus driver updates

   - binder driver updates

   - extcon driver updates

   - dma_buf module namespaces added (will cause a build error in arm64
     for allmodconfig, but that change is on its way through the drm
     tree)

   - lkdtm driver updates

   - pvpanic driver updates

Commit f839f14e24 ("phy: qcom-qmp: Add sc8180x PCIe support") added
SC8180X PCIe tables, but used sm8250_qmp_pcie_serdes_tbl as a serdes
table because of the copy paste error. Commit bfccd9a71a ("phy:

by pointing serdes_tbl to sc8180x_qmp_pcie_serdes_tbl, however the
serdes_tbl_num field was not updated to use sc8180x table. So let's now
fix the serdes_tbl_num field too.

This patch adds support of new optional properties to configure the tune
interface of the phys of stm32-usbphyc.
Properties are optional, that's why each property is skipped if not
found (-EINVAL).
Phy tuning is restored on resume because if deep low power state is
achieved, phy tuning configuration is reset.
