Subject: [PATCH 04/15] IB/hfi1: Remove no-op QSFP reset code
Date: Thu, 12 May 2016 10:22:51 -0700	[thread overview]
Message-ID: <20160512172250.9741.86084.stgit@scvm10.sc.intel.com> (raw)
In-Reply-To: <20160512172050.9741.84190.stgit-9QXIwq+3FY+1XWohqUldA0EOCMrvLtNR@public.gmane.org>

From: Dean Luick <dean.luick-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

The RESET_N bit of the ASIC_QSFPn_OE register is not used by
the hardware.  Remove code that tries to use it - it does
nothing.
