Subject: [PATCH 2/2] spi/coldfire-qspi: Drop extra calls to spi_master_get in suspend/resume functions
Date: Thu, 16 Aug 2012 20:26:00 -0700	[thread overview]
Message-ID: <1345173960-6138-2-git-send-email-linux@roeck-us.net> (raw)
In-Reply-To: <1345173960-6138-1-git-send-email-linux-0h96xk9xTtrk1uMJSBkQmQ@public.gmane.org>

Suspend and resume functions call spi_master_get() without matching
spi_master_put(). The extra references are unnecessary and cause
subsequent module unload attempts to fail, so drop the calls.
