Subject: [PATCH] mmc: vub3000: fix control-request direction
Date: Fri, 21 May 2021 15:30:26 +0200 [thread overview]
Message-ID: <20210521133026.17296-1-johan@kernel.org> (raw)
The direction of the pipe argument must match the request-type direction
bit or control requests may fail depending on the host-controller-driver
implementation.
Fix the SET_ROM_WAIT_STATES request which erroneously used
usb_rcvctrlpipe().
Fixes: 88095e7b473a ("mmc: Add new VUB300 USB-to-SD/SDIO/MMC driver")
Cc: stable@vger.kernel.org # 3.0
