[PATCH v2 1/3] winebus.sys: Add devtype parameter to get_device_subsystem_info().

[Ivo Ivanov]

From: Ivo Ivanov <logos128(a)gmail.com>

Narrow the search for a parent subsystem to a specific devtype.
For the usb subsystem in particular, only the "usb_device"
devtype includes all the necessary attributes, so no need to
iterate through the usb interfaces.

[PATCH v2 2/3] winebus.sys: Always parse uevent PRODUCT= line on input subsystem.

[Rémi Bernon]

From: Rémi Bernon <rbernon(a)codeweavers.com>

Letting the usb subsystem override what the input/hid subsystems have
parsed previously, unless it's on the bluetooth bus where the usb device
is the bluetooth dongle.

Fixes an issue with the device revision (bcdDevice) not being extracted
from the usb subsystem, causing the bcdHID to be extracted in error.

[PATCH v2 3/3] winebus.sys: Read vendor/product/serial strings from the usb subsystem.

[Ivo Ivanov]

From: Ivo Ivanov <logos128(a)gmail.com>

Fixes an issue with the product name including the manufacturer
in the same string.
Both attributes are correctly extracted from the usb subsystem.
