Subject: [PATCH] atmel_lcdfb: fix usage of wrong registers in suspend/resume
Date: Mon, 06 Jun 2011 08:50:51 +0000 [thread overview]
Message-ID: <1307350251-5767-1-git-send-email-h.feurstein@gmail.com> (raw)
I assume the intention was to set the contrast value to 0 and not
the contrast control register (in atmel_lcdfb_suspend). And in
atmel_lcdfb_resume the contrast value should be restored.
