Subject: [PATCH] MMC: Do not set unsupported bits in OCR response
Date: Tue, 10 Oct 2006 16:23:39 +0300 [thread overview]
Message-ID: <20061010132339.GA14769@mail.solidboot.com> (raw)
In-Reply-To: <20061009165317.GA6431@flint.arm.linux.org.uk>
The card might go to inactive state (according to specification), if
there are unsupported bits set in the OCR.
