Re: [RFC v10 1/1] leds: asus-aura-scsi: Add ASUS Aura RGB LED driver for ROG NVMe enclosures

[Liang Haowen]

The 0/1 cover letter for this series was blocked by my outgoing
mail provider and never reached the lists; resending its content
here.

v10, wiring the driver into the tree. A driver source file
without Kconfig and Makefile entries is dead code in the tree,
so this version adds them: LEDS_ASUS_AURA_SCSI sits inside the
LEDS_CLASS_MULTICOLOR block in drivers/leds/rgb/Kconfig with a
depends on SCSI, and the Makefile line beside the other rgb
drivers.

The only code change is strscpy() passing the buffer size
explicitly now. The two-argument form is supported by the
current string.h macros, but with the size written out the call
builds on any tree.

v10 was verified on hardware again after these changes: built
with clang against 7.2.4, the four LEDs set to independent
colours and confirmed by eye, 60 sequential and 100 concurrent
updates, the sdev deleted mid-write (zero splats, clean
detach), rmmod after detach, and a fresh attach through a host
scan.

The interface direction is unchanged from v9: the LED side will
move onto Marco's Dynamic Lighting class
(OpenGamingCollective/linux-unstable#17) once that settles.
