[PATCH RFC 036/111] staging: etnaviv: ensure cleanup of reservation object

[Lucas Stach]

From: Russell King <rmk+kernel at arm.linux.org.uk>

The embedded reservation object is always initialised whenever we create
an etnaviv buffer object, but it is not always cleaned up.  Arrange this
to be clearer: always initialise the embedded reservation object
directly, and always clean the embedded reservation object up when
removing a buffer object.
