<id>5a876e8742b709ed4d3db068fe453515609e0402</id>
<content type='text'>
commit c8e4e5bdb62a5ac6f860ebcaaf7b467b62f453f1 upstream.

Corrected the register to check the 64-bit pointer
capability state. 64-bit pointer implementation capability
was checking in wrong register, which causes the BDC
enumeration failure in 64-bit memory address.

Fixes: efed421a94e6 ("usb: gadget: Add UDC driver for
Broadcom USB3.0 device controller IP BDC")

SuperSpeed support").

In the case of ClearPortFeature and USB_PORT_FEAT_POWER, simply clear
the right bit regardless of what the wValue is.

<title>usb: dwc2: Make sure we disconnect the gadget state</title>

[ Upstream commit dad3f793f20fbb5c0c342f0f5a0bdf69a4d76089 ]

I had seen some odd behavior with HiKey's usb-gadget interface
that I finally seemed to have chased down. Basically every other
time I plugged in the OTG port, the gadget interface would
properly initialize. The other times, I'd get a big WARN_ON
in dwc2_hsotg_init_fifo() about the fifo_map not being clear.

Ends up if we don't disconnect the gadget state, the fifo-map
doesn't get cleared properly, which causes WARN_ON messages and
also results in the device not properly being setup as a gadget
every other time the OTG port is connected.

So this patch adds a call to dwc2_hsotg_disconnect() in the
reset path so the state is properly cleared.

With it, the gadget interface initializes properly on every
plug in.

commit 1a087f032111a88e826877449dfb93ceb22b78b9 upstream.

When I debug a kernel crash issue in funcitonfs, found ffs_data.ref
overflowed, While functionfs is unmounting, ffs_data is put twice.

Commit 43938613c6fd ("drivers, usb: convert ffs_data.ref from atomic_t to
refcount_t") can avoid refcount overflow, but that is risk some situations.
So no need put ffs data in ffs_fs_kill_sb, already put in ffs_data_closed.

The issue can be reproduced in Mediatek mt6763 SoC, ffs for ADB device.
KASAN enabled configuration reports use-after-free errro.

<title>usb: quirks: add control message delay for 1b1c:1b20</title>

commit cb88a0588717ba6c756cb5972d75766b273a6817 upstream.

Corsair Strafe RGB keyboard does not respond to usb control messages
sometimes and hence generates timeouts.

Commit de3af5bf259d ("usb: quirks: add delay init quirk for Corsair
Strafe RGB keyboard") tried to fix those timeouts by adding
USB_QUIRK_DELAY_INIT.

Unfortunately, even with this quirk timeouts of usb_control_msg()
can still be seen, but with a lower frequency (approx. 1 out of 15):

[   29.103520] usb 1-8: string descriptor 0 read error: -110
[   34.363097] usb 1-8: can't set config #1, error -110

Adding further delays to different locations where usb control
messages are issued just moves the timeouts to other locations,
e.g.:

[   35.400533] usbhid 1-8:1.0: can't add hid device: -110
[   35.401014] usbhid: probe of 1-8:1.0 failed with error -110

The only way to reliably avoid those issues is having a pause after
each usb control message. In approx. 200 boot cycles no more timeouts
were seen.

Addionaly, keep USB_QUIRK_DELAY_INIT as it turned out to be necessary
to have the delay in hub_port_connect() after hub_port_init().

The overall boot time seems not to be influenced by these additional
delays, even on fast machines and lightweight distributions.

commit 5126a504b63d82785eaece3a9c30c660b313785a upstream.

This USB-SATA controller seems to be similar with JMicron bridge
152d:2566 already on the list. Adding it here fixes "Invalid
field in cdb" errors.
