The .set_mmss and .setmmss64 ops are only called when the RTC is not
providing an implementation for the .set_time callback.
On alpha, .set_time is provided so .set_mmss64 is never called. Remove the
unused code.

Previously we called pci_probe_reset_function() in this path:
pci_sysfs_init # late_initcall
for_each_pci_dev(dev)
pci_create_sysfs_dev_files(dev)
pci_create_capabilities_sysfs(dev)
pci_probe_reset_function
From: Bjorn Helgaas
We probe every device for whether it supports reset so we can tell whether
to create a sysfs "reset" file for it. We do that probe in
pci_init_capabilities() during enumeration and save the result in
dev->reset_fn. The result doesn't depend on any other devices on the bus

The PCI core currently uses a late_initcall to probe each device for
whether it supports reset. This is dangerous because a driver may have
already claimed the device by this point, and the PCI core should not
interfere with the driver by touching the device on its own.

Command DB is a simple database in the shared memory of QCOM SoCs, that
provides information regarding shared resources. Some shared resources
in the SoC have properties that are probed dynamically at boot by the

Command DB provides information on shared resources like clocks,
regulators etc., probed at boot by the remote subsytem and made
available in shared memory.

Hi!
Camera should work on N900, with v4.16-rc1. Autofocus should work;
flash is in the queue.
This patch is needed for non-square image. Patched v4l-utils is very
much recommened for taking photos.
Sakari: any ideas about this one? This is the bug I showed you in
Prague...
Best regards,
Fix a coding style warning from checkpatch.pl. Use GNU extensions to create
references to the results of problem macro arguments when they are evaluated so
that they can be used safely multiple times.

kernel, it has not been necessary to use smp_read_barrier_depends().
Similarly, commit 59ecbbe7b31c ("locking/barriers: Kill

There is a single error path where tfile->napi_mutex is left unlocked.
It can lead to a deadlock.
