From cdcd141c95f0c2b88e0b0869028c320cd031a23b Mon Sep 17 00:00:00 2001 From: Ondrej Zary Date: Sat, 6 Apr 2013 14:21:36 -0300 Subject: [PATCH] [media] tuner-core: Change config from unsigned int to void * config looks like a hack that was added to tuner-core to allow some configuration of TDA8290 tuner (it's not used by any other driver). But with the new configuration options of tda8290 driver (no_i2c_gate and std_map), it's no longer sufficient. Change config to be void * instead, which allows passing tuner-dependent config struct to drivers. Also update saa7134 driver to reflect this change (no other driver uses this).
