Subject: [PATCH 1/2] mmc: core: Ensure cmd_completion is initialized
Date: Fri, 1 Dec 2017 14:55:30 +0200 [thread overview]
Message-ID: <1512132931-12380-2-git-send-email-adrian.hunter@intel.com> (raw)
In-Reply-To: <1512132931-12380-1-git-send-email-adrian.hunter@intel.com>
mmc_test now uses mmc_start_request() to test sending commands during
"ongoing" asynchronous transfers, i.e. tests:
Commands during non-blocking read - use Set Block Count (CMD23)
Commands during non-blocking write - use Set Block Count (CMD23)
mmc_start_request() was not initializing cmd_completion, but cmd_completion
is used by "ongoing" transfers, so move initialization of cmd_completion
into making mmc_start_request().
Fixes: cb39f61e9b1e ("mmc: core: Export a few functions needed for blkmq support")
