In <db3b9e990e75573402cda22faf933760f076c033> ("Staging: VME: move VME drivers out of staging") the vme code, board and bridge drivers were moved out of the staging tree, remaining only the VME user device driver. Since this driver is the only one remaining in staging, such multi-level structure confuses more than helps. The current structure is as follows: - drivers/staging/vme/ Makefile devices/ Kconfig Makefile vme_user.c vme_user.h The top-level Makefile has the only function of calling another Makefile into the devices/ subdirectory. This latter only compiles the vme_user driver, since there is no other in the staging tree. This patch removes the unnecessary Makefile from the 'vme/' dir, move the contents of 'vme/devices' into the 'vme/' dir, and renames it to 'vme_user/' (the driver name), allowing a straightforward understanding of this driver's contents. Furthermore, it updates the MAINTAINERS file to properly reflect the new paths.
