This means that people need to find and install the firmware themselves before the touchscreen will work Some UEFI/x86 tablets with an icn8505 touchscreen have a copy of the fw embedded in their UEFI boot-services code. This commit makes the icn8505 driver use the new firmware_request_platform function, which will fallback to looking for such an embedded copy when direct filesystem lookup fails. This will make the touchscreen work OOTB on devices where there is a fw copy embedded in the UEFI code.
