The controller never transitions into mission mode. This appears to be due to the modem device expecting the various contexts and transfer rings to have fields in little endian order in memory, but the driver constructs them in native endianness. Fix MHI event, channel and command contexts and TRE handling macros to use explicit conversion to little endian. Mark fields in relevant structures as little endian to document this requirement.

This is caused by using find_last_bit which takes an unsigned long* while the state is passed in as an enum mhi_pm_state which will be of int size.

Add a timeout parameter to xhci_reset(), and adjust it back to 250ms when called from xhci_stop() or xhci_shutdown() where interrupts are disabled, and successful reset isn't that critical. This solves issues when deactivating host mode on platforms like SM8450. For now don't change the timeout if xHC is reset in xhci_resume(). No issues are reported for it, and we need the reset to succeed. Locking around that reset needs to be revisited later. Additionally change the signed integer timeout parameter in xhci_handshake() to a u64 to match the timeout value we pass to readl_poll_timeout_atomic() Fixes: 22ceac191211 ("xhci: Increase reset timeout for Renesas 720201 host.")

[PATCH v2] misc/mei: Add NULL check to component match callback functions

Component match callback functions need to check if expected data is passed to them.
