From 85bfb4af14c89fea929973e79a55901877992127 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 15 Jan 2020 17:35:52 +0100 Subject: [PATCH] Input: icn8505 - Switch to firmware_request_platform for retreiving the fw Unfortunately sofar we have been unable to get permission to redistribute icn8505 touchscreen firmwares in linux-firmware. 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.
