From 02aea4fb640cdc4018e0a6d34e235eb63e4482d7 Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Thu, 26 Jun 2008 04:58:30 -0300 Subject: [PATCH] V4L/DVB (8301): sms1xxx: add capability to define device-specific firmware filenames Add the capability to define device-specific firmware filenames for the SMS1150, with a mechanism to fall back to the generic firmware if the device-specific firmware is not present.
