Subject: [PATCH 3/3] sm501fb: suspend and resume fb if it exists
Date: Sat,  4 Nov 2017 21:24:21 +0000	[thread overview]
Message-ID: <1509830661-7384-3-git-send-email-sudipm.mukherjee@gmail.com> (raw)
In-Reply-To: <1509830661-7384-1-git-send-email-sudipm.mukherjee@gmail.com>

There are cases when panel and crt both are not defined and only one of
them is defined and initialized. In such cases, suspend or resume it
only if it is defined.
