vesa_init_done isn't a reliable guard for the mutex init. If vesa_configure() doesn't find valid VESA info it will not set vesa_init_done, but the lock will remain initialized. Revert r303076 and use MTX_SYSINIT to deterministically init the lock. Reviewed by: royger MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D7290
