[PATCH -next v2] drm/msm/dpu: Convert to DEFINE_SHOW_ATTRIBUTE
From: Qinglang Miao
Date: Fri Sep 18 2020 - 22:51:43 EST
Use DEFINE_SHOW_ATTRIBUTE macro to simplify the code.
Signed-off-by: Qinglang Miao <miaoqinglang@xxxxxxxxxx>

v2: based on linux-next(20200917), and can be applied to
mainline cleanly now.
