Fix following warnings: openprom.c:510:2: warning: 'tmp' may be used uninitialized in this function [-Wmaybe-uninitialized] openprom.c:503:3: warning: 'str' may be used uninitialized in this function [-Wmaybe-uninitialized] openprom.c:459:8: warning: 'str' may be used uninitialized in this function [-Wmaybe-uninitialized] openprom.c:422:7: warning: 'str' may be used uninitialized in this function [-Wmaybe-uninitialized] Fixed by introducing PTR_ERR etc. This simplified the code as a nice side effect.
