From 1bacb2df3bc999dcad21e9aab6bdb60d6dc7bc02 Mon Sep 17 00:00:00 2001 From: Ondrej Zary Date: Sat, 6 Apr 2013 14:29:29 -0300 Subject: [media] tda8290: change magic LNA config values to enum Use enum instead of magic values for LNA config in tda8290. Update tda827x, tda18271 and saa7134 to use the enum too.
