We want to skip only tx/rx_iface clocks and not ref_clk_src as well. Fix the jump label accordingly.

Fix build errors in phy-rockchip-inno-usb2.c. The driver uses extcon interfaces so it should depend on EXTCON.

The error paths of the common qcom-ufs functions for registering the phy, acquiring clocks and acquiring regulators all print specific error messages before returning an error, so there is no value in printing yet another - more generic - message when this occur. Reviewed-by:

The fact that a regulator is always-on is a property of the regulator, not a specific consumer. Implementing this in the driver leads to a system behaviour that is dependent on if the Qualcomm UFS PHY was ever (partially) probed. If the specific regulator should be always on in a particular device, mark it so by specifying "regulator-always-on" in the regulator node. Reviewed-by:

When regulator_get() tries to resolve a regulator supply but fail to find a matching property in DeviceTree it returns a dummy regulator, if a matching supply is specified but unavailable the regulator core will return an error. Based on this we should not ignore errors upon failing to acquire the optional "vddp-ref-clk" supply. Reviewed-by:

Bjorn Andersson authored
Upon failing to acquire regulator supplies the qcom-ufs driver calls kfree() on the devm allocated memory used to store the name of the regulator, leading to devres corruption. Rather than switching to using the appropriate free function the patch acknowledge the fact that "name" is always a constant string and we don't actually need to create a local copy of it, but rather just reference the constant string.

The driver reports that it always uses a low-latency mode by returning the ASYNC_LOW_LATENCY flag through TIOCGSERIAL. Even if this behaviour could not be changed, this may have made some sense prior to 7a9a65ce ("cdc-acm: Fix long standing abuse of tty->low_latency") which removed the unconditional setting of the corresponding tty low_latency flag (something which had always been broken in itself). Since the driver does not have a low-latency mode, let's drop the flag. Signed-off-by:

Felipe writes: USB: changes for v4.11 Here's the big pull request for the Gadget API. Again the majority of changes sit in dwc2 driver. Most important changes contain a workaround for GOTGCTL being wrong, a sleep-inside-spinlock fix and the big series of cleanups on dwc2. One important thing on dwc3 is that we don't anymore need gadget drivers to cope with unaligned OUT transfers for us. We have support for appending one extra chained TRB to align transfer ourselves. Apart from these, the usual set of typos, non-critical fixes, etc.
