An old patch added a 'return' statement after each BUG() in this driver,
which was necessary at the time, but has become redundant after the BUG()
definition was updated to handle this properly.
gcc-11 now warns about one such instance, where the 'return' statement
was incorrectly indented:
drivers/gpu/drm/omapdrm/dss/dispc.c: In function ‘pixinc’:
drivers/gpu/drm/omapdrm/dss/dispc.c:2093:9: error: this ‘else’ clause does not guard... [-Werror=misleading-indentation]
2093 | else
| ^~~~
drivers/gpu/drm/omapdrm/dss/dispc.c:2095:17: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘else’
2095 | return 0;
| ^~~~~~
Address this by removing the return again and changing the BUG()
to be unconditional to make this more intuitive.
