From 495e3ff365425f9b69884ddde36047184f37c2bd Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Sun, 19 Aug 2012 10:44:17 -0700 Subject: spi/pl022: Fix device remove function The call sequence spi_alloc_master/spi_register_master/spi_unregister_master is complete; it reduces the device reference count to zero, which results in device memory being freed. An extra call to spi_master_put is unnecessary and results in an access to free memory. Drop it.
