Date: Fri, 25 Sep 2015 12:28:37 -0300 [thread overview]
Message-ID: <1443194918-5867-3-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1443194918-5867-1-git-send-email-acme@kernel.org>
From: Adrian Hunter <adrian.hunter@intel.com>
no_force_psb was dropped as a late change to the kernel driver.
Consequently, remove it from the documentation.
