Hello Benjamin,
In file 'windfarm_pm121'.c:
If this branch is true:

printk(KERN_WARNING pm121: %s fan config not found

loop_names[loop_id]);
goto fail;
}
control that is NULL will suffer a
make the Freescale PCI driver get, prepare and enable the PCI clock
during probe(); the clock gets put upon device shutdown by the devm
approach
clock lookup is non-fatal as not all platforms may provide clock specs
in their device tree or implement a device tree based clock provider,
but failure
this series introduces support for the common clock framework (CCF,
COMMON_CLK Kconfig option) in the PowerPC based MPC512x platform, which
brings device tree based clock lookup as well
at subsystem maintainers:
this series was streamlined for conflict free application through the
subsystems'
introduce a dt-bindings/ header file for MPC512x clocks,
providing symbolic identifiers for those SoC clocks which
clients will reference from their device tree nodes

this addresses the clock driver aka provider's side of clocks
- introduce a 'clocks' subtree with an 'osc' node for the crystal
or oscillator SoC input (fixed frequency)
- the 'clock@f00' clock-control-module node references the 'osc' for
its input, and is another provider for all the clocks
this change implements a clock driver for the MPC512x PowerPC platform
which follows the COMMON_CLK approach and uses common clock drivers
shared with other platforms
this driver implements the publicly announced set of clocks (those
listed in the dt-bindings header file), as well as generates
extend the recently added COMMON_CLK platform support for MPC512x such
that it works with incomplete device tree data which lacks clock specs

the setup before the change was

was built, which implements the clk.h API but always returns -ENOSYS

device tree based clock lookup, prepare and unprepare for clocks,
work with frequencies not dividers, call the appropriate clk_*()

migration to common clock support has completed

In some scene, e.g openstack CI, PR guest can trigger sc 1 frequently,
this patch optimizes the path by directly delivering BOOK3S_INTERRUPT_SYSCALL
