[ Upstream commit c40ad6b7fcd35bc4d36db820c7737e1aa18d5d41 ]
Pass UFS device information to vendor-specific variant callback
"apply_dev_quirks" because some platform vendors need to know such
information to apply special handling or quirks in specific devices.
At the same time, modify existing vendor implementations according to the
new interface for those vendor drivers which will be built-in or built as a
module alone with UFS core driver.

If, for some bizarre reason, the compiler decided to split up the write
of STE DWORD 0, we could end up making a partial structure valid.
Although this probably won't happen, follow the example of the
context-descriptor code and use WRITE_ONCE() to ensure atomicity of the
write.

[ Upstream commit 91b6dec32e5c25fbdbb564d1e5af23764ec17ef1 ]
We currently have musb_set_vbus() called from two different paths. Mostly
it gets called from the USB PHY via omap_musb_set_mailbox(), but in some
cases it can get also called from musb_stage0_irq() rather via .set_vbus:
(musb_set_host [musb_hdrc])
(omap2430_musb_set_vbus [omap2430])
(musb_stage0_irq [musb_hdrc])
(musb_interrupt [musb_hdrc])
(omap2430_musb_interrupt [omap2430])
This is racy and will not work with introducing generic helper functions
for musb_set_host() and musb_set_peripheral(). We want to get rid of the
busy loops in favor of usleep_range().
Let's just get rid of .set_vbus for omap2430 glue layer and let the PHY
code handle VBUS with musb_set_vbus(). Note that in the follow-up patch
we can completely remove omap2430_musb_set_vbus(), but let's do it in a
separate patch as this change may actually turn out to be needed as a
fix.

If reloaded in a loop it will quickly trigger a WARN message:

Fix by calling cpuhp_remove_multi_state on remove like several other

Also fix the cleanup logic on probe error paths: add the missing

This is because the msm_gpio_irq_set_wake() function calls
irq_set_irq_wake() as a backup in case the irq comes in during the path
to idle. Given that we're calling irqchip functions from within an
irqchip we need to set the lockdep class to be different for this child
controller vs. the default one that the parent irqchip gets.
This used to be done before this driver was converted to hierarchical
irq domains in commit e35a6ae0eb3a ("pinctrl/msm: Setup GPIO chip in
hierarchy") via the gpiochip_irq_map() function. With hierarchical irq
domains this function has been replaced by
gpiochip_hierarchy_irq_domain_alloc(). Therefore, set the lockdep class
like was done previously in the irq domain path so we can avoid this
lockdep warning.

The existing code allows changing the data device when the thin-pool
target is reloaded.
This capability is not required and only complicates device lifetime
guarantees. This can cause crashes like the one reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=1788596
where the kernel tries to issue a flush bio located in a structure that
was already freed.
Take the first step to simplifying the thin-pool's data device lifetime
by disallowing changing it. Like the thin-pool's metadata device, the
data device is now set in pool_create() and it cannot be changed for a
given thin-pool.

Add delay to make sure that audio urbs are not sent too early.
Otherwise the device hangs. Windows driver makes ~2s delay, so use
about the same time delay value.
snd_usb_apply_boot_quirk() is called 3 times for my MOTU M4, which
is an overkill. Thus a quirk that is called only once is implemented.
Also send two vendor-specific control messages before and after
the delay. This behaviour is blindly copied from the Windows driver.

The DM365 platform has a strange quirk (only present when using ancient
u-boot - mainline u-boot v2013.01 and later works fine) where if we
enable the second half of the timer in periodic mode before we do its
initialization - the time won't start flowing and we can't boot.
When using more recent u-boot, we can enable the timer, then reinitialize
it and all works fine.
To work around this issue only enable clockevents once tim34 is
initialized i.e. move clockevents_config_and_register() below tim34
initialization.

First, printk() is NMI-context safe now since the safe printk() has been
implemented and it already has an irq_work to make NMI-context safe.
Second, this NMI irq_work actually does not work if a NMI handler causes
panic by watchdog timeout. It has no chance to run in such case, while
the safe printk() will flush its per-cpu buffers before panicking.
While at it, repurpose the irq_work callback into a function which
concentrates the NMI duration checking and makes the code easier to
follow.

The logic in __efi_enter_virtual_mode() does a number of steps in
sequence, all of which may fail in one way or the other. In most
cases, we simply print an error and disable EFI runtime services
support, but in some cases, we BUG() or panic() and bring down the
system when encountering conditions that we could easily handle in
the same way.
While at it, replace a pointless page-to-virt-phys conversion with
one that goes straight from struct page to physical.
