Subject: [PATCH v12 07/10] Input: silead - Switch to firmware_request_platform for retreiving the fw
Date: Wed, 15 Jan 2020 17:35:51 +0100
Message-ID: <20200115163554.101315-8-hdegoede@redhat.com> (raw)
In-Reply-To: <20200115163554.101315-1-hdegoede@redhat.com>

Unfortunately sofar we have been unable to get permission to redistribute
Silead 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 a Silead touchscreen have a copy of the fw
embedded in their UEFI boot-services code.

This commit makes the silead 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.
