System may crash after unloading ipmi_si.ko module
because a timer may remain and fire after the module cleaned up resources.
cleanup_one_si() contains the following processing.
/*
* Make sure that interrupts, the timer and the thread are
* stopped and will not run again
Some functions from refcount_t API provide different
memory ordering guarantees that their atomic counterparts.
This adds a document outlining these differences.

The Light Pulse Generator (LPG) is a PWM-block found in a wide range of
PMICs from Qualcomm. It can operate on fixed parameters or based on a
lookup-table, altering the duty cycle over time - which provides the
means for e.g. hardware assisted transitions of LED brightness.

Some LED controllers have support for autonomously controlling
brightness over time, according to some preprogrammed pattern or
function.
This adds a new optional operator that LED class drivers can implement

In case of error returned by 'q6v5_xfer_mem_ownership', we must free
some resources before returning.
In 'q6v5_mpss_init_image()', add a new label to undo a previous
