The problem I'm trying to solve is that modern Windows applications are
executing system call instructions directly from the application's code
without going through the WinAPI. This breaks Wine emulation, because

LPASS variants have their own soc specific clocks that needs to be
enabled for MI2S audio support. Added a common variable in drvdata to
initialize such clocks using bulk clk api. Such clock names is
defined in variants specific data and needs to fetched during init.
This patch chain add audio support for SC7180 soc by doing the required
modification in existing common lpass-cpu/lpass-platform driver.

Refactor the mapping from handle flags to desc flags into a helper
function.
The assign_bit is overkill where it is replacing the set_bit cases, as is
rechecking bits known to be clear in some circumstances, but the DRY
simplification more than makes up for any performance degradation,
especially
Rename 'filep' and 'filp' to 'file' to be consistent with other use
and improve readability.

Replace usage of atomic_notifier_call_chain with
blocking_notifier_call_chain as the notifier function,
lineinfo_changed_notify, calls gpio_desc_to_lineinfo,
which calls pinctrl_gpio_can_use_line, which can sleep.
The chain isn't being called from an atomic context so the

This collection of patches provides improvements to or
address minor problems in gpiolib-cdev.
The majority of the patches (1-7, 9-11) have been pulled directly from
my "gpio: cdev: add uAPI V2" patch set, as they are not related to any
uAPI changes.
The remaining patches were either split out of
Move gpiolib-sysfs function declarations into their own header.
These functions are in gpiolib-sysfs.c, and are only required by gpiolib.c,
and so should be in a module header, not gpiolib.h.
This brings gpiolib-sysfs into line with gpiolib-cdev, and is another step
towards removing the sysfs
Sort the includes of gpiolib-cdev.c to make it easier to identify if a
module is included and to avoid duplication.

Right, it makes sense to avoid nodes without memory, hence loosing portions
of CMA reservation intended for HugeTLB. N_MEMORY is better than
