From 1462612cb3172068c3f4dca1778e5fb115191c70 Mon Sep 17 00:00:00 2001 From: Jemma Denson Date: Tue, 5 May 2015 17:18:11 -0300 Subject: [PATCH] [media] cx24120: Remove additional calls to read_status get_frontend was making a call to read_status, which is being called periodically anyway. Have read_status store fe_status in the state struct instead and use that within get_frontend.
