I think your tree makes most sense for this patch, since it only touches

Patch series adding support for ROHM BD71837 PMIC.
BD71837 is a programmable Power Management IC for powering single-core,
dual-core, and quad-core SoC’s such as NXP-i.MX 8M. It is optimized for
low BOM cost and compact solution footprint. It integrates 8 buck
regulators and 7 LDO’s to provide

Do not directly lock/unlock uart_port->lock, but use uart_port_lock
helper macros.
The patch also renames serial_core internal macros uart_port_lock()
and uart_port_unlock() to uart_port_ref_lock() and to
uart_port_unlock_deref() correspondingly.

TTY port spin_lock is one of the locks that can cause a
printk-recursion deadlock, thus we need to lock it from
printk_safe context. E.g.
ioctl()
tty_ioctl()
spin_lock(_port->lock)
printk()
call_console_drivers()
foo_console_write()
spin_lock(_port->lock)
tty_wakeup()

So, if the suggestion is to use an existing property "unit", I am fine
with it, if people agree to it.
FALLOC_FL_NO_HIDE_STALE flag must be set if user want to issue
a discard request for block devices. But vfs_fallocate() will
return with an error -EOPNOTSUPP indicating lack of support
if this flag is set.
fix it by allowing FALLOC_FL_NO_HIDE_STALE flag in vfs_fallocate

I wonder if something like the following might actually work. IIUC
cpuset.c comment [1], callback_lock is the one to actually take if one
needs to only query cpusets.

Some of the rpmsg devices need to switch on power domains to communicate
with remote processor. For example on Qualcomm DB820c platform LPASS
power domain needs to switched on for any kind of audio services.
This patch adds the missing power domain support in rpmsg core.

Per Section 8.4.7.1.3 of ACPI 6.2, The platform provides performance

When the devfreq driver and the governor driver are built as modules,
the call to devfreq_add_device() fails because the governor driver is
not loaded at the time the devfreq driver loads. The devfreq driver has
a build dependency on the governor but also should have a runtime
dependency. We need
