Subject: Re: [PATCH V7 4/7] LPC: Support the device-tree LPC host on Hip06/Hip07 (fwd)
Date: Tue, 14 Mar 2017 06:37:20 +0100 (CET) [thread overview]
Message-ID: <alpine.DEB.2.20.1703140635090.3516@hadrien> (raw)
Line 460 looks suspicious. Can tmprange be different than range but not
be an ERR_PTR? If so, lpcdev->io_host will have an invalid value.
