When a control URB is submitted, the direction indicated by URB's pipe member is supposed to match the direction indicated by the setup packet's bRequestType member. A mismatch could lead to trouble, depending on which field the host controller drivers use for determining the actual direction. This shouldn't ever happen; it would represent a careless bug in a kernel driver somewhere. This patch adds a dev_WARN_ONCE to let people know about the potential problem. Suggested-by:

When vbus auto discharge is enabled, TCPCI based TCPC transitions into Attached.SNK/Attached.SRC state. During PR_SWAP, TCPCI based TCPC would disconnect when partner changes power roles. TCPC has to be moved APPLY RC state during PR_SWAP. This is done by ROLE_CONTROL.CC1 != ROLE_CONTROL.CC2 and POWER_CONTROL.AutodischargeDisconnect is 0. Once the swap sequence is done, AutoDischargeDisconnect is re-enabled. Fixes: f321a02c ("usb: typec: tcpm: Implement enabling Auto Discharge disconnect support") Reviewed-by:

On start-up, we can get a spurious session request interrupt with nothing connected. After that the devctl session bit will silently clear, but the musb hardware is never idled until a cable is plugged in, or the glue layer module is reloaded. Let's just check the session bit again in 3 seconds in peripheral mode to catch the issue. Signed-off-by:

Looks like we are missing suspend and resume functions for pm_ops that are needed to idle the hardware for system suspend for 2430 glue layer. We can rely on the driver internal PM runtime state, and call driver functions to idle the hardware on suspend if needed. There is no need to add a dependency to PM runtime for system suspend here.

On the Realtek high-speed Hub(0bda:5487), the port which has wakeup enabled_descendants will sometimes timeout when setting PORT_SUSPEND feature. After checking the PORT_SUSPEND bit in wPortStatus, it is already set which means the port has been suspended. We should treat it suspended to make sure it will be resumed correctly. Acked-by:

There is no need to store the dentry for a fixed filename that we have the string for. So just have debugfs look it up when we need it to remove the file, no need to store it anywhere locally. Note, this driver is broken in that debugfs will not work for more than one instance of the device it supports. But given that this patch does not change that, and no one has ever seemed to notice, it must not be an issue...
