2021-08-26Revert "usb: xhci-mtk: Do not use xhci's virt_dev in drop_endpoint"Chunfeng Yun
I find the patch introduce some issues, e.g. 1. oops happens when xhci_gen_setup() failed, and hash is not init but try to destroy it; 2. memory leakage happens when fail to insert ep, need free sch_ep, or insert ep after insert int list; 3. memory leakage happens when fail to allocate sch_array, need destroy rhashtable; 4. it's better to check ep->hcpriv when drop ep; so prefer to revert this patch, and resend it after the issues are fixed. This reverts commit b8731209958a1dffccc2888121f4c0280c990550.

As discussed in following patch: https://patchwork.kernel.org/patch/12420339 No need calculate number of uframes again, but should use value form check_sch_tt(), if we plan to remove extra CS, also can do it in check_sch_tt().

2021-08-26usbip:vhci_hcd USB port can get stuck in the disabled stateShuah Khan
When a remote usb device is attached to the local Virtual USB Host Controller Root Hub port, the bound device driver may send a port reset command. vhci_hcd accepts port resets only when the device doesn't have port address assigned to it. When reset happens device is in assigned/used state and vhci_hcd rejects it leaving the port in a stuck state. This problem was found when a blue-tooth or xbox wireless dongle was passed through using usbip. A few drivers reset the port during probe including mt76 driver specific to this bug report. Fix the problem with a change to honor reset requests when device is in used state (VDEV_ST_USED).

2021-08-26regmap: teach regmap to use raw spinlocks if requested in the configVladimir Oltean
Some drivers might access regmap in a context where a raw spinlock is held. An example is drivers/irqchip/irq-ls-extirq.c, which calls regmap_update_bits() from struct irq_chip :: irq_set_type, which is a method called by __irq_set_trigger() under the desc->lock raw spin lock. Since desc->lock is a raw spin lock and the regmap internal lock for mmio is a plain spinlock (which can become sleepable on RT), this is an invalid locking scheme and we get a splat stating that this is a "[ BUG: Invalid wait context ]". It seems reasonable for regmap to have an option use a raw spinlock too, so add that in the config such that drivers can request it.

quirk set" This reverts commit 5d5323a6f3625f101dbfa94ba3ef7706cce38760. That commit effectively disabled Intel host initiated U1/U2 lpm for devices with periodic endpoints. Before that commit we disabled host initiated U1/U2 lpm if the exit latency was larger than any periodic endpoint service interval, this is according to xhci spec xhci 1.1 specification section 4.23.5.2 After that commit we incorrectly checked that service interval was smaller than U1/U2 inactivity timeout. This is not relevant, and can't happen for Intel hosts as previously set U1/U2 timeout = 105% * service interval. Patch claimed it solved cases where devices can't be enumerated because of bandwidth issues. This might be true but it's a side effect of accidentally turning off lpm. exit latency calculations have been revised since then Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/20210820123503.2605901-5-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2021-08-26xhci: Fix failure to give back some cached cancelled URBs.Mathias Nyman
Only TDs with status TD_CLEARING_CACHE will be given back after cache is cleared with a set TR deq command. xhci_invalidate_cached_td() failed to set the TD_CLEARING_CACHE status for some cancelled TDs as it assumed an endpoint only needs to clear the TD it stopped on. This isn't always true. For example with streams enabled an endpoint may have several stream rings, each stopping on a different TDs. Note that if an endpoint has several stream rings, the current code will still only clear the cache of the stream pointed to by the last cancelled TD in the cancel list. This patch only focus on making sure all canceled TDs are given back, avoiding hung task after device removal. Another fix to solve clearing the caches of all stream rings with cancelled TDs is needed, but not as urgent. This issue was simultanously discovered and debugged by by Tao Wang, with a slightly different fix proposal.

Description of the bits has been kindly provided by Realtek. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2021-08-26staging: r8188eu: remove ethernet.h header fileMichael Straube
There are only two definitions from ethernet.h used in the driver. Namely: #define ETHERNET_HEADER_SIZE 14 /* Ethernet Header Length */ #define LLC_HEADER_SIZE 6 /* LLC Header Length */ Both are only used in the file core/rtw_recv.c. Replace the usage of ETHERNET_HEADER_SIZE with ETH_HLEN, move the definition of LLC_HEADER_SIZE into rtw_recv.h and remove the now unused ethernet.h header file.
