[svn-r22998] Description:

    Clean up warnings and bring changes from Coverity branch back to trunk:

r20451:
Fixed coverity 810

r20454:
Purpose: Fix coverity issue 816

Description: Modified various file drivers to always check the return value from
H5P_get_driver_info.

r20455:
Purpose: Cleanup fix for coverity issue 816

Description: Removed redundant check for "fa" in H5FD_core_open.


Tested on:
    Mac OSX/64 10.8.2 (amazon) w/debug
    (Too minor to require h5committest)
