From b73bb2ab97eb7840d0f4fc285936024100f59a6d Mon Sep 17 00:00:00 2001 From: Daniel Scheller Date: Tue, 14 Mar 2017 19:22:37 -0300 Subject: [media] dvb-frontends/drxk: don't log errors on unsupported operation mode When fe_ops.read_status is called and no channel is tuned (yet), the subsequent calls to get_lock_status() causes the kernel log to be filled with drxk: Error -22 on get_lock_status which either means a NULL pointer was passed for the p_lock_status var, or neither QAM nor OFDM/DVBT operation mode are active. Instead of filling the kernel log in the latter case, print out a message to the debug level and return 0 (this isn't used in the calling drxk_get_stats() anyway).
