[PATCH 1/3] staging: vme: use image mutex for ioctl()

This implements more granular locking in vme_user_ioctl() by using separate locks for each devfs device. This also provides a synchronization between vme_user_read(), vme_user_write() and vme_user_ioctl(). Signed-off-by: Dmitry Kalinkin Cc: Igor Alekseev ---
