Subject: i2c-i801: Check for vendor Fujitsu before probing for apanel
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6aa1464d5482cc8f6f026ebb12d94b77a58c823b;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

i2c-i801: Check for vendor Fujitsu before probing for apanel

Scanning the BIOS memory for the apanel information is costly, so
avoid doing it on non-Fujitsu machines.
