From bb07bd6b6851120ac9b25bb315d62d9782d2c345 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 11 Feb 2016 14:24:23 -0200 Subject: [media] allow overriding the driver name On USB drivers, the dev struct is usually filled with the USB device. That would mean that the name of the driver specified by media_device.dev.driver.name would be "usb", instead of the name of the actual driver that created the media entity. Add an optional field at the internal struct to allow drivers to override the driver name.
