From: Stefan Richter Date: Tue, 26 Aug 2008 23:24:25 +0000 (+0200) Subject: ieee1394: inherit ud vendor_id from node vendor_id X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9c939e4df432fe4ed17bdbf7bc14111ec51ef7c9;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ieee1394: inherit ud vendor_id from node vendor_id While Module_Vendor_ID in the configuration ROM's root directory is mandatory, there often aren't vendor IDs in unit directories. This affects the new firedtv driver which is meant to be auto-loaded and matched only for vendor-specific devices. We now always copy ne->vendor_id into ud->vendor_id before we scan a unit directory (and fill in a possibly present vendor ID from there). This way, the root directory's vendor ID is used as fallback in the "uevent" environment for modprobe'ing per module alias when a node was plugged in, and in the driver match routine when protocol drivers are bound to unit directories. It will however not be used as sysfs attribute of a unit directory device.
