From fd83e2487e9149d8cd7c8b1e7d6f0e5231b79f8a Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Mon, 20 Nov 2006 17:03:48 -0300 Subject: [PATCH] V4L/DVB (4869): Lgh06xf: use return value of dvb_pll_configure() Use return value of dvb_pll_configure() to fill priv->frequency In lgh06xf_set_params: Rename int variable "err" to "result". Remove needless calculation of the set frequency, since this value is now being returned by dvb_pll_configure().
