Subject: [PATCH v1 3/3] mmc: sdio: print correct UHS mode during card detection
Date: Tue, 4 Dec 2012 17:06:20 +0530 [thread overview]
Message-ID: <1354620980-23764-4-git-send-email-subhashj@codeaurora.org> (raw)
In-Reply-To: <1354620980-23764-1-git-send-email-subhashj@codeaurora.org>
When SDIO3.0 card is detected, incorrect bus speed mode
is printed as part of card detection print in kernel logs.
This change fixes it so that user won't be confused by
looking at incorrect card detection message in logs.
