From 7dc1b8844eb3e0a91911f20736db87f4876e14b4 Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Sat, 21 Jun 2008 22:13:42 -0300 Subject: V4L/DVB (8098): xc5000: add module option to load firmware during driver attach The xc5000 firmware download process can be slow on certain devices. Add a module option, "init_fw" to perform the firmware download during xc5000_attach(), which would get the firmware download over with well before any tune request is made. When this option is enabled, it will reduce the time it takes to get a signal lock during the first tune after driver load, but will add a few seconds to the driver initialization.
