From 80f8568f47306dc4453bb6630ac607f22ca4c7b4 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 29 May 2013 06:59:39 -0300 Subject: [PATCH] [media] cx23885: remove g_chip_ident Replace g_chip_ident by g_chip_info. Note that the IR support is implemented as a subdev, so this part no longer needs to be handled as a 'bridge' chip.
