Subject: Re: [PATCH 3/8] drivers/mfd: Add lookup table for Panel Control as GPIO signal
Date: Wed, 29 Apr 2015 15:29:18 +0100	[thread overview]
Message-ID: <20150429142918.GV9169@x1> (raw)
In-Reply-To: <1430316005-16480-4-git-send-email-shobhit.kumar@intel.com>

By the way, your subject lines are messed up.

They should adhere to the conventions laid down by the Maintainers.

`git log --oneline -- drivers/<subsystem>`

> On some Intel SoC platforms, the panel enable/disable signals are

> 
> v2: Make the lookup table static (Thierry)
>     Remove the lookup table during driver remove (Thierry)
