Subject: [PATCH 0/3] staging: most: replace BUG_ON() with WARN_ON_ONCE()

This small series replaces BUG_ON() calls in three staging MOST drivers
with WARN_ON_ONCE() and appropriate error handling.

The affected drivers are:

  - drivers/staging/most/i2c/i2c.c
  - drivers/staging/most/dim2/dim2.c
  - drivers/staging/most/video/video.c

All changes are mechanical and do not alter runtime behavior, except that
the kernel will now log a warning instead of panicking if a driver
invariant is violated.

Tested with checkpatch.pl and compile-tested (make M=drivers/staging/most).
