Subject: [PATCH v2] media: remove bdisp_dbg_declare() and hva_dbg_declare()
Date:   Sat,  1 Dec 2018 21:04:25 -0500
Message-Id: <20181202020425.9189-1-tiny.windzz@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

We already have the DEFINE_SHOW_ATTRIBUTE.There is no need to define
bdisp_dbg_declare and hva_dbg_declare,so remove them.Also use
DEFINE_SHOW_ATTRIBUTE to simplify some code.

Changes in v2:
-delete fimc_is_debugfs_open
