The `LocalModule` type is the type of the module created by `module!`,
`module_pci_driver!`, `module_platform_driver!`, etc.
Since the exact type of the module is sometimes generated on the fly by
the listed macros, provide an alias.
This is first used by the `module_firmware!` macro.

edid-decode gained recently support to check that infoframes are
compliant and match the EDID the monitor exposes.
Since the HDMI helpers provide those infoframes in debugfs, it makes it
easy to check from userspace that the drivers (and helpers) behave
properly.
Let's document it.

We have had documentation for the public functions in the HDMI helpers,
but those were never referenced anywhere and thus not compiled as part
of the doc.
Let's add a section.

This series removes the remaining dependencies on fbdev from the

The event FB_EVENT_BLANK sends the new blank state in the event's
data field. Also send the old state. It's an additional field in the
data array; existing receivers won't notice the difference.
The backlight subsystem currently tracks blank state per display per
backlight. That is not optimal as

Change return type to bool for better clarity. Update the kernel doc
comment accordingly, including fixing "@value" to "@val" and adjusting
examples. Also mark the function with __attribute_const__ to allow
potential compiler optimizations.

Several parts of the kernel contain redundant implementations of parity
calculations for 16/32/64-bit values. Introduces generic
parity16/32/64() helpers in bitops.h, providing a standardized
and optimized implementation.
Subsequent patches refactor various kernel components to replace

Add parity16(), parity32(), and parity64() to compute the parity of
16-bit, 32-bit, and 64-bit values, respectively. Each function extends
parity8() by XOR-ing upper and lower halves, reducing the input size
progressively.
