xhci-mtk depends on xhci's internal virt_dev when it retrieves its internal data from usb_host_endpoint both in add_endpoint and drop_endpoint callbacks. But when setup packet was retired by transaction errors in xhci_setup_device() path, a virt_dev for the slot is newly created with real_port 0. This leads to xhci-mtks's NULL pointer dereference from drop_endpoint callback as xhci-mtk assumes that virt_dev's real_port is always started from one. The similar problems were addressed by [1] but that can't cover the failure cases from setup_device. This patch drops the usages of xhci's virt_dev in xhci-mtk's drop_endpoint callback by adopting rhashtable for searching mtk's schedule entity from a given usb_host_endpoint pointer instead of searching a linked list. So mtk's drop_endpoint callback doesn't have to rely on virt_dev at all. [1] https://lore.kernel.org/r/1617179142-2681-2-git-send-email-chunfeng.yun@mediatek.comSigned-off-by:

When polling for a setup or clear of a register field we were sleeping in atomic context but using a very tight sleep interval. Since the use cases for this poll mechanism are only in setup and stop paths, and in practice this poll is not used most of the times but needs to be there to comply to hardware setup times, remove the sleep time and make the poll loop tighter.

This patch adds support for scatter gather transfers.

Due to no platforms use a multi-funtion pin to detect VBUS status until now when support dual role mode, prefer not to support it anymore; Another reason is that the controller doesn't support idle status, the dual role port works as device or as host, using an IDDIG pin is good enough, this will help to save another multi-function pin; And fix a typo of 'neede'; Last modify example using VBUS to turn on/off device, for device only mode, the driver doesn't get extcon.

gcc doesn't care, but clang quite reasonably pointed out that the recent commit e9ba16e6 ("smpboot: Mark idle_init() as __always_inlined to work around aggressive compiler un-inlining") did some really odd things: kernel/smpboot.c:50:20: warning: duplicate 'inline' declaration specifier [-Wduplicate-decl-specifier] static inline void __always_inline idle_init(unsigned int cpu) ^ which not only has that duplicate inlining specifier, but the new __always_inline was put in the wrong place of the function definition. We put the storage class specifiers (ie things like "static" and "extern") first, and the type information after that. And while the compiler may not care, we put the inline specifier before the types. So it should be just static __always_inline void idle_init(unsigned int cpu) instead.
