-+ request_firmware() hotplug interface:
-+ ------------------------------------
-+	Copyright (C) 2003 Manuel Estrada Sainz <ranty@debian.org>
-+
-+ Why:
-+ ---
-+
-+ Today, the most extended way to use firmware in the Linux kernel is linking
-+ it statically in a header file. Which has political and technical issues:
-+
-+  1) Some firmware is not legal to redistribute.
-+  2) The firmware occupies memory permanently, even though it often is just
-+     used once.
-+  3) Some people, like the Debian crowd, don't consider some firmware free
-+     enough and remove entire drivers (e.g.: keyspan).
-+
-+ about in-kernel persistence:
-+ ---------------------------
-+ Under some circumstances, as explained below, it would be interesting to keep
-+ firmware images in non-swappable kernel memory or even in the kernel image
-+ (probably within initramfs).
-+
-+ Note that this functionality has not been implemented.
-+
-+ - Why OPTIONAL in-kernel persistence may be a good idea sometimes:
-+ 
-+	- If the device that needs the firmware is needed to access the
-+	  filesystem. When upon some error the device has to be reset and the
-+	  firmware reloaded, it won't be possible to get it from userspace.
-+	  e.g.:
-+		- A diskless client with a network card that needs firmware.
-+		- The filesystem is stored in a disk behind an scsi device
-+		  that needs firmware.
-+	- Replacing buggy DSDT/SSDT ACPI tables on boot.
-+	  Note: this would require the persistent objects to be included
-+	  within the kernel image, probably within initramfs.
-+	  
-+   And the same device can be needed to access the filesystem or not depending
-+   on the setup, so I think that the choice on what firmware to make
-+   persistent should be left to userspace.
-+
-+ - Why register_firmware()+__init can be useful:
-+ 	- For boot devices needing firmware.
-+	- To make the transition easier:
-+		The firmware can be declared __init and register_firmware()
-+		called on module_init. Then the firmware is warranted to be
-+		there even if "firmware hotplug userspace" is not there yet or
-+		it doesn't yet provide the needed firmware.
-+		Once the firmware is widely available in userspace, it can be
-+		removed from the kernel. Or made optional (CONFIG_.*_FIRMWARE).
-+
-+	In either case, if firmware hotplug support is there, it can move the
-+	firmware out of kernel memory into the real filesystem for later
-+	usage.
-+
-+	Note: If persistence is implemented on top of initramfs,
-+	register_firmware() may not be appropriate.
