Alexander Graf d273845ecb ACPI: allow longer device IDs
We create a list of ACPI "PNP" IDs which contains _HID, _CID, and CLS
entries of the respective devices. However, when making structs for
matching, we squeeze those IDs into acpi_device_id, which only has 9
bytes space to store the identifier. The subsystem actually captures the
full length of the IDs, and the modalias has the full length, but this
struct we use for matching is limited. It originally had 16 bytes, but
was changed to only have 9 in 6543becf26 ("mod/file2alias: make
modalias generation safe for cross compiling"), presumably on the theory
that it would match the ACPI spec so it didn't matter.

Unfortunately, while most people adhere to the ACPI specs, Microsoft
decided that its VM Generation Counter device [1] should only be
identifiable by _CID with a value of "VM_Gen_Counter", which is longer
than 9 characters.

To allow device drivers to match identifiers that exceed the 9 byte
limit, this simply ups the length to 16, just like it was before the
aforementioned commit. Empirical testing indicates that this
doesn't actually increase vmlinux size on 64-bit, because the ulong in
the same struct caused there to be 7 bytes of padding anyway, and when
doing a s/M/Y/g i386_defconfig build, the bzImage only increased by
0.0055%, so negligible.

This patch is a prerequisite to add support for VMGenID in Linux, the
subsequent patch in this series. It has been confirmed to also work on
the udev/modalias side in userspace.

* @idVendor: USB vendor ID for a device; numbers are assigned

* @idProduct: Vendor-assigned product ID.
* @bcdDevice_lo: Low end of range of vendor-assigned product version numbers.
* This is also used to identify individual product versions, for
* a range consisting of a single device.
* @bcdDevice_hi: High end of version number range. The range of product
* versions is inclusive.
* @bDeviceClass: Class of device; numbers are assigned
* by the USB forum. Products may choose to implement classes,
* or be vendor-specific. Device classes specify behavior of all
* the interfaces on a device.
* @bDeviceSubClass: Subclass of device; associated with bDeviceClass.
* @bDeviceProtocol: Protocol of device; associated with bDeviceClass.
* @bInterfaceClass: Class of interface; numbers are assigned
* by the USB forum. Products may choose to implement classes,
* or be vendor-specific. Interface classes specify behavior only
* of a given interface; other interfaces may support other classes.
* @bInterfaceSubClass: Subclass of interface; associated with bInterfaceClass.
* @bInterfaceProtocol: Protocol of interface; associated with bInterfaceClass.
* @bInterfaceNumber: Number of interface; composite devices may use
* fixed interface numbers to differentiate between vendor-specific
* interfaces.
* @driver_info: Holds information used by the driver. Usually it holds
* a pointer to a descriptor understood by the driver, or perhaps
* device flags.
*
* In most cases, drivers will create a table of device IDs by using
* USB_DEVICE(), or similar macros designed for that purpose.
* They will then export it to userspace using MODULE_DEVICE_TABLE(),
* and provide it to the USB core through their usb_driver structure.
*
* See the usb_match_id() function for information about how matches are
* performed. Briefly, you will normally use one of several macros to help
* construct these entries. Each entry you provide will either identify
* one or more specific products, or will identify a class of products
* which have agreed to behave the same. You should put the more specific
* matches towards the beginning of your table, so that driver_info can
* record quirks of specific products.
