Subject: [PATCH 1/2] media: dvb-core add new flag exit flag value for resume
Date: Thu, 24 Jul 2014 10:02:14 -0600 [thread overview]
Message-ID: <e40686f1c07261e606bf5eee3facf3b139e51b6c.1406215947.git.shuah.kh@samsung.com> (raw)

Some fe drivers will have to do additional initialization
in their fe ops.init interfaces when called during resume.
Without the additional initialization, fe and tuner driver
resume fails. A new fe exit flag value DVB_FE_DEVICE_RESUME
is necessary to detect resume case. This patch adds a new
define and changes dvb_frontend_resume() to set it prior to
calling fe init and tuner init calls and resets it back to
DVB_FE_NO_EXIT once fe and tuner init is done.
