Subject: [PATCH] spi/s3c64xx: Drop extra calls to spi_master_get in suspend/remove functions
Date: Thu, 16 Aug 2012 20:14:25 -0700 [thread overview]
Message-ID: <1345173265-1721-1-git-send-email-linux@roeck-us.net> (raw)
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. Drop the calls.
