From ccca00d6d7c2d6cec282ac3e3942032268d50fe4 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Wed, 30 Dec 2015 14:43:59 -0200 Subject: [PATCH] [media] nuvoton-cir: improve logical device handling Only enable the logical devices after the registers have been initialized. The call to nvt_enable_logical_dev in nvt_resume is not needed as this is done implicitely by nvt_cir_regs_init now.
