Subject: [PATCH] media: em28xx - remove reset_resume interface
Date: Wed, 9 Jul 2014 14:36:03 -0600 [thread overview]
Message-ID: <1404938163-27461-1-git-send-email-shuah.kh@samsung.com> (raw)
em28xx uses resume interface as its reset_resume interface.
If usb device is reset during suspend, reset_resume doesn't
do the necessary initialization which leads to resume failure.
Many systems don't maintain do not maintain suspend current to
the USB host controllers during hibernation. Remove reset_resume
to allow disconnect to be called followed by device restore
sequence.
