Subject: [PATCH v2] media: remove bdisp_dbg_declare() and hva_dbg_declare()
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.
Signed-off-by: Yangtao Li <tiny.windzz@...il.com>

Changes in v2:
-delete fimc_is_debugfs_open
